Amory Ames is a wealthy young woman who questions her marriage to her notoriously charming playboy husband, Milo. Looking for a change, she accepts a request for help from her former fiance, Gil Trent. Amory accompanies Gil to the luxurious Brightwell Hotel in an attempt to circumvent the marriage of his sister, Emmeline, to Rupert Howe, a disreputable ladies' man. Amory sees in the situation a grim reflection of her own floundering marriage. There is more than her happiness at stake, however, when Rupert is murdered and Gil is arrested for the crime. Amory is determined to prove his innocence and find the real killer. As the stakes grow higher and the line between friend and foe becomes less clear, Amory must decide where her heart lies and catch the killer before she, too, becomes a victim.
