In the play, Sir John Bevil is encouraging his son, Bevil Jr., to marry the wealthy Lucinda, daughter of Mr. Sealand. John Bevil was quite the rake in his day, and he is trying to encourage his son to settle down with a wife and start a family. Bevil Jr., however, is faced with a dilemma, for though he is set to marry Lucinda, he is not in love with her, but his good friend Myrtle is. Bevil Jr. is in love with Indiana, a poor woman whose mother died when Indiana was seven. Indiana has been raised by her Aunt Isabella (Mr. Sealand's sister). She is the daughter of Mr. Sealand by his first wife, though no one realizes it. Mr. Sealand is intent on marrying his daughter Lucinda to Bevil Jr., but Mrs. Sealand, Mr. Sealand's second wife and Lucinda's mother, is intent on her marrying the young coxcomb Cimberton, because of his vast fortune and also because he is Mrs. Sealand's cousin. However, because of his fortune, Cimberton cannot marry without the consent of his Uncle Geoffrey or his counsel of lawyers. So Bevil Jr. and Myrtle devise a scheme where Myrtle and Bevil Jr.'s servant, Tom, will disguise themselves as Sir Geoffrey's lawyers, Bramble and Target, in order to delay the wedding proceedings. They arrive at Mr. Sealand's house in disguise, and convince Cimberton and Mrs. Sealand that the marriage absolutely cannot proceed without Sir Geoffrey's physical presence to sign away part of the estate. In the meantime, Sir John and Mr. Sealand discuss Bevil Jr.'s morals, for it has been discovered that he has been visiting a woman of lower class on a frequent basis. Mr. Sealand decides to go and visit this young woman so that he may judge Bevil Jr.'s moral conduct for himself, and Sir John and his servant Humphrey discuss the implication of marrying his son off as a bargaining chip to double the estate rather than letting Bevil Jr. choose a wife of his own. The next day, Phillis, Lucinda's maid, arrives at Bevil Jr.'s lodgings with news that Sir Geoffrey is expected in town at any moment, and suggests that Myrtle disguise himself as Sir Geoffrey in order to further delay the marriage proceedings. Myrtle arrives at Mr. Sealand's house disguised at Sir Geoffrey. Mrs. Sealand is in a hurry to marry Lucinda to Cimberton while her husband is away, she begins proceedings for a wedding. When Mr. Sealand arrives at Isabella and Indiana's lodgings, Isabella recognizes him, but he does not recognize her. He talks to Indiana, listens to her sad story, and while she is in a crying fit she drops a bracelet on the floor, and Mr. Sealand recognizes it as the bracelet he gave his first wife just before they were separated. Mr. Sealand is happy to be reunited with his daughter and sister, and in this moment insists that Indiana marry Bevil Jr. Isabella leaves that instant to get Bevil Jr. and arrives with Sir John Bevil, Bevil Jr., Mrs. Sealand, Cimberton, Myrtle disguised as Sir Geoffrey, and Lucinda. In this final scene, Mr. Sealand says he would rather have Myrtle marry Lucinda because he never likes Cimberton, and Cimberton will not marry Lucinda because her dowry has just been halved by the discovery of the other daughter. He leaves, and Myrtle reveals himself. In the end, the moral of the story, given by Sir John, is that the happiness of the young is provided by good virtue, honesty and "Providence."
