Act I
Sisters Hellena and Florinda's fates have been decided for them by the men in their life, mainly their brother and father. Hellena is to enter the convent after Carnival has ended. Florinda's father wants her to marry elderly Don Vincentio and her brother, Don Pedro, wants her to marry Don Antonio. However, she has feelings for Belville, an English colonel. The women, not approving of these plans, dress up for Carnival in an attempt to avoid their chosen fates.
Belville, Blunt, Frederick, and Willmore are also enjoying Carnival when they run into Florinda, Hellena, and Valeria (their cousin). Willmore and Hellena flirt with one another; Hellena agrees to meet Willmore again later. Meanwhile, Lucetta begins to seduce Blunt. Florinda begins to set up a meeting with Belville when she sees her brother approaching. She hastily gives him a letter and runs off with Hellena and Valeria. Florinda's letter contains instructions for Belville to come to her garden at ten that night and carry her off. Blunt sneaks off with Lucetta.
Act II
Willmore, Belville, and Frederick go to see Angellica, a famous courtesan. Angellica's servants hang up a portrait of her outside of her house. The Englishmen are astounded by her beauty, but leave when they realise they do not have the money to buy her—one thousand crowns a month. Don Pedro enters and sees the picture and the price. He has the money and runs to fetch it.
Angellica laments that no one has taken her up because of the high price, but when she learns of Don Pedro and Don Antonio, both of whom are rich, she decides to pursue them, then goes back inside. Pedro soon enters from one side of the stage, and Antonio enters from the other; both men are masked. Antonio is also struck by Angellica's portrait and wonders out loud if he could get away with sleeping with Angellica and still marry Florinda. At the mention of Florinda, Pedro recognizes Antonio. They fight. Willmore and Blunt enter and break them up. Pedro challenges Antonio to a duel the next day over Angellica. Antonio accepts.
Meanwhile, Willmore sees a smaller picture of Angellica and tries to steal it. Antonio tells him to put it back. Willmore refuses and says that Antonio has the money to pay for the real thing. Angellica enters just in time to see another fight break out. Angellica asks Willmore to speak with her inside as she was initially very excited and impressed by him. Willmore goes, despite Belville and Frederick's fears that Angellica is angry with him. Willmore tries to persuade Angellica to sleep with him for free. Normally Angellica would not agree to this, but she has fallen in love with Willmore, with his wits and his way. She agrees, despite the warnings from her maidservant Moretta.
Act III
Hellena says that she is not in love, but she cannot stop thinking about Willmore. The women see Belville, Blunt, and Frederick approach, and eavesdrop on the men. Belville, Blunt and Frederick have come to retrieve Willmore from Angellica because he has been inside with her for two hours. Willmore comes out and brags about having enjoyed Angellica's charms for free.
Hellena, who has seen and heard everything Willmore said, comes out of hiding and pretends as if nothing has transpired. As Willmore begins to flirt with her again, Angellica enters, masked, and sees Willmore betraying the vows he made to her. Hellena finally reveals her face to Willmore, who praises her beauty. This is the last straw for Angellica. She orders one of her servants to find out who Hellena is and storms out. Hellena asks what Willmore was doing in Angellica's house; he denies that anything transpired. Hellena then attacks him, quoting to him what he had just said about Angellica. She makes Willmore promise never to see Angellica again. Meanwhile, Florinda and Valeria are testing Belville's loyalty to Florinda by trying to seduce him while he doesn't know who they are. He stands firm. The women exit, but Florinda leaves Belville with a locket. Belville recognizes Florinda's picture in the locket and resolves to rescue her that night, with Willmore and Frederick's help. Meanwhile, Blunt is tricked out of his money and clothes by Lucetta.
Florinda waits in her garden for Belville wearing a nightgown. Willmore enters, drunk, mistakes Florinda for a prostitute, and tries to persuade her to sleep with him. When she resists he attempts to rape her, but when Belville and Frederick enter, Florinda runs off. Willmore and Belville almost fight, but Frederick intervenes. The noise however, brings Pedro and his servants to the garden. A fight breaks out and the English are driven off.
Willmore tries to explain to a furious Belville that he didn't know who Florinda was and mistook her for a whore. Belville and Frederick leave to find Florinda.
Antonio enters, hoping that his page has paid Angellica so he can sleep with her. Willmore sees this and starts a fight with Antonio. Antonio falls, wounded. Willmore believes he has killed Antonio and runs off. Belville runs in, fearing that it is Willmore who has been hurt. Soldiers enter and arrest Belville, believing him to be the attacker. Antonio finds his strength and orders Belville taken to his house.
Act IV
Don Antonio does not believe that Belville is innocent of having injured him; however, he offers Belville an alternative to imprisonment. Since Antonio is wounded and cannot duel Pedro, Belville could dress up as Antonio and go instead. Belville agrees, believing the fight to be over Florinda.
Florinda frets that Belville did not come to her window as planned, and fears that the impending duel is between Belville and Pedro. Pedro enters, masked, and reveals that he will be fighting Antonio, relieving some of Florinda's fears. Belville enters, disguised as Antonio. Florinda runs in to stop them. Belville is confused as to why Florinda would defend his rival but they push her away and fight. Florinda stops them again just as Belville disarms Pedro. She begs him spare Pedro. Belville lays his sword at Florinda's feet and swears his love to her. The action redeems him in Pedro's eyes, so he gives his sister to the man he believes to be Antonio, demanding that they get married at once. Florinda protests, but Belville secretly lifts his mask to show her who he is.
Just then, Willmore and Frederick enter. Wilmore greets him by embrace. The embrace makes Belville drop his mask. Pedro now refuses to allow the wedding, since it was Antonio's fight, not Belville's. He drags Florinda away, accusing her of trying to trick him. Belville, furious at being thwarted yet again, turns on Willmore and chases him away. Angellica enters with her servants Moretta and Sebastian, furious that Willmore loves Hellena. Sebastian runs after Willmore to bring him back. Angellica accuses Willmore of having another woman. Willmore, as usual, attempts to charm her back.
Hellena enters disguised as a man. She decides to interfere and approaches Angellica pretending to be one of Hellena's servants. She tells a story about a young girl who fell in love and was left standing at the altar because her lover came to Angellica. Then she reveals the lover to be Willmore. Angellica is moved by the story, Willmore is only excited and impatient to find out who the woman in question is. Suddenly, Willmore recognizes Hellena and figures out what's going on. He turns to Angellica and starts describing Hellena as a Gypsy, ugly, a monkey, etc. He tells Hellena to go back to her mistress. Angellica is outraged with Willmore and vows to take revenge and sends Willmore away. Willmore exits with an aside in which he says he plans to try to win Hellena back.
Florinda and Valeria enter, disguised in different costumes, having momentarily escaped Pedro. Then Don Pedro, Belville, and Willmore enter. Pedro and Belville seem to be having a serious conversation. Willmore follows Florinda when she walks past, again thinking she is a courtesan. Frederick comes in and relates Blunt's misadventures to Belville and Pedro. They all go off to find him. Florinda reenters, still being chased by Willmore. Then Hellena arrives and sees Willmore pursuing this "unknown" woman. She sends a page to find out where they go. Florinda ducks into a door to avoid Willmore; it turns out to be Belville's house. The page Hellena sent goes off to relay the information.
Blunt is staying in Belville's house. Florinda enters, sees Blunt and asks him for help. Blunt then attempts to rape her based on his new contempt for women. Frederick enters, also convinced that Florinda is a prostitute, and joins Blunt. Florinda gives them a diamond ring and asks them to consult Belville. Frederick fears that she might be a lady of some worth and asks Blunt to wait. Blunt is still sceptical but agrees. Frederick locks Florinda in a room.
Act V
Belville, Willmore, Frederick, and Pedro break into Blunt's room and laugh at him. Blunt says that just a moment before there was a wench in his chamber and shows them the ring Florinda gave him. Belville recognizes the ring as the one he gave Florinda when they exchanged vows. The other men, unaware that the girl is Florinda, decide to let her out and have their way with her. They draw swords to see who has the longest. Don Pedro wins and unlocks Florinda's door.
Florinda runs in, still masked and pursued by Pedro. She is saved when Valeria arrives and persuades Pedro to leave by telling him that Callis knows where Florinda is hiding. Once he is gone, Florinda removes her mask. Valeria tells Belville and Florinda to get married quickly, before Pedro returns. Frederick and Valeria decide to get married as well. Belville sends a boy to fetch a priest. Frederick and Blunt realise that they almost raped Florinda and apologise, returning the ring. Florinda forgives them. Belville, Florinda, Valeria, and Frederick exit to get married; Blunt goes off to see a tailor. Willmore stays behind to guard against Pedro's return.
Angellica enters, pointing a pistol at Willmore; she rages at him while threatening him with the gun. Willmore offers to pay her for her services; she refuses. As she prepares to kill him, Don Antonio enters with his arm in a sling. He takes the gun from Angellica, then recognises Willmore as the man who stole Angellica's picture. He offers to shoot Willmore. Pedro enters. Angellica decides to let Willmore live, and leaves. Don Pedro asks why Don Antonio missed the duel; Antonio tells him what happened, and leaves in a huff. Pedro decides to give Florinda to Belville in revenge. Willmore informs him that the marriage has already occurred. Pedro exits.
Hellena enters, still in boy's clothes, and banters with Willmore, who wants to sleep with her but doesn't want to marry her. Hellena finally convinces him for marriage. Pedro, Belville, Florinda, Frederick, and Valeria enter. They learn of Willmore and Hellena's engagement and Pedro approves, tired of fearing for his sister's honour (virginity). Blunt enters in a Spanish habit, looking ridiculous. Music plays and masquers from Carnival come in dancing. The play ends with vows of love between Hellena and Willmore.
