Musical comedy star Pat Donahue is the toast of Broadway in the show Gypsy Love . On the last night of the musical's highly successful run, his teenage son, Pat, Jr., causes a stir when, from the audience, he recites his father's well-worn farewell speech along with him. Pat soon discovers that his son and his girl friend, Judy Watkins, have come to New York to borrow the play's old sets and costumes for their boarding school's theatrical workshop. When theatrical producer Max Wilson is convinced by Pat, Jr. to direct the workshop's next production, Prentis Johns, the noted English playwright, agrees to join Max in order to work on his new musical, Everything Goes . Prentis is so taken by the teenagers that he allows them to stage his play as a work-in-progress. After seeing the workshop's production, Prentis convinces Max to cast Pat, Jr. in the lead of the play's Broadway production, a role his father had been planning to play. In order to prepare for the role, Pat, Jr. goes to see his father at a vacation lodge. With Pat away on a fishing trip, Pat, Jr. wanders down to the lake to rehearse. His singing attracts the attention of Lynn Andrews, a cook book author, and her secretary, Jean Mathews. Thinking that Pat, Jr.'s heart has been broken, Lynn tries to take his mind off his heartache by pretending to be a damsel in distress. Her plan works until Pat, Jr. overhears the two women laughing at him. Lynn and Pat, Jr. soon make up, and he becomes convinced that the older woman is in love with him. When Pat and Sam Bassett, his agent, return to the lodge, Pat, Jr. finally learns that he has been cast in his father's part. Unwilling to tell his father the truth, Pat, Jr. then pretends to have been cast in another production. In order to keep his father from receiving Max's explanatory phone call that evening, Pat, Jr. persuades his father to join him for dinner with Lynn. When Pat, Jr. sneaks back up to his father's room to take Max's call, Sam overhears the young man turn down the part out of loyalty to Pat. The agent then tries to convince the elder Donahue to skip the Prentis play and take some time off, with little success. Meanwhile, Pat and Lynn begin to fall for each other, though he still thinks she is in love with Pat, Jr. When Lynn meets Judy, the women decide to combine forces at a party that night. Finally alone together, Pat and Lynn proclaim their love for each other and he proposes. Pat then informs Max and Prentis that he will be unavailable for their show, as he plans to be on his honeymoon, so suggests Pat, Jr. for his part. Like his father before him, Pat, Jr. becomes a big Broadway star, with Judy by his side, onstage and off.
