Jack Strong and Minnie Lee are sweethearts. He is called out of town on business and meets his friend Clover, who requests him to act as escort to the chaperone of a supper party which he is giving in honor of his fiancée, an actress. Jack accepts with very bad grace, and some kind friend informs Minnie that Jack Strong was seen at a popular café with a chum and two actresses. When he returns, Minnie gives him no chance to explain the incident and a bitter quarrel follows. Jack goes to his old friend, Lund, a retired artist, with his troubles and the latter, in the role of peacemaker, invites them both, unknown to each other, to an afternoon tea. Leighton and Kitty, another young couple, are also invited. By prearranged plan, Leighton bestows particular attention upon Minnie, while Kitty proves a charming listener to all Jack has to say. Noting the growing jealousy between Minnie and Jack, Lund smiles to himself. Later, Jack is angrily telling Lund of the heartache the "green-eyed monster" is causing him. When they see Minnie coming Jack hides in an alcove. Minnie sobs out her troubles to the kindly old gentleman, but obstinately refuses to make up with Jack. Lund then shows her a letter from Glover explaining the whole affair. She is very humble, and fearing she has lost Jack forever, bursts out crying again. Lund then beckons to Jack, who gently takes Minnie in his arms. A happy reconciliation follows between the lovers. Leighton and Kitty join them, while Lund, with a smile of content, lights his pipe and dreams of the days when he was young and in love.
