John Constable, a writer, falls prey to the designs of scheming widow Margaret Alloway to the dismay of his young wife Kitty. Feigning interest in Johns work, the widow offers to collaborate on his new book, Womens Struggles, but when she convinces him to dine with her on Kittys birthday, the neglected wife decides to retaliate. After attending the opera with handsome bachelor Harry Travers, Kitty accepts an invitation to share supper in his rooms, leaving a note for her husband. Aware of Harrys questionable reputation with women, John panics, but by the time he arrives at Harrys apartment, Kitty has disappeared. Following a series of incidents in which the widow, her suitor Teddy Sylvester, Travers, and the Constables are discovered in compromising situations that actually are innocent, John realizes that he far prefers Kitty to the widow and again becomes a loving husband.
