George Barnert Callender, playwright and an excellent swimmer, is at Marvis Bay for the production of his play Fate's Footballs, shortly to be put on there. He is on the pier, dwelling on the play's troubles, particularly its star Arthur Mifflin, when he sees a very attractive girl in the water. Straining to follow her as she swims beneath him, he falls from the pier, and is just about to swim off when she grasps him and begins to drag him to shore. He lets her do this, hoping to form an acquaintanceship, and on the shore they meet and she offers to teach him to swim.
They meet again later, and he learns her name is Mary Vaughan, staying at the same hotel as George with an aunt. Next day, the troupe arrive to perform George's play, and Mifflin, full of ideas to promote the piece, heads out on a boat trip with George. Explaining it is a stunt to attract attention to the play, Mifflin upsets the boat, expecting George to drag him to safety. George refuses, however, as it would spoil things with Mary, and makes Mifflin to pretend to be the rescuer.
Mary's suspicions are aroused by the repeat rescuing, and recalls having seen George before, swimming strongly at another resort. She is furious with him, but Mifflin explains George's initial gallantry and reluctance to repeat the act, and all is forgiven.
Later, with George's play a success in London, he is accompanied into his box by a lady...
