A jilted lover finds himself implicated in a murder
When John Holland proposed to his girlfriend, Tracy, she imposed a 31-day waiting period before they could see each other again. It’s day 30, and Holland travels to her Long Island home for their reunion, only to receive the shock of his life when he meets Tracy’s fiancé, Roger Drake. Tracy’s mother invites Holland to stay there and win back Tracy’s love, and within a few hours, Drake is dead.
As it turns out, Drake was a private detective hired by Tracy as a test for her beloved—and it looks like Holland failed. Meanwhile, Drake’s boss, hardnosed detective Sam Crombie, descends on the home, looking to avenge his comrade.
