Bright young novelist Mabel Vere is engaged to Gerald Wantage, a prig who angrily objects when she advertises for a husband in order to elicit ideas for her new book. Mabel's roommate, Maud Bray, a physical culture expert, frightens away the less desirable suitors, while the writer responds to the more interesting letters, and soon becomes embroiled in a number of adventures. One of her applicants is a butler, whose employer, Noel Corcoran, also has answered the ad. Noel informs Mabel that Gerald has bet the other members of his club that she will answer no more letters. Angered, she responds to several particularly lurid ones, after which she and Gerald break off their engagement. Having fallen in love with Mabel, Noel proposes and is accepted.
