An ad appears in a London paper, looking for a woman with a sense of adventure and no ties. A young woman lands the job, says goodbye to her two roommates, and never contacts them again. Six weeks later, one of the other roommates finds the same ad in the paper and applies. She is hired immediately, and despite her close friendship with her roommate, never writes or calls. Four months later, the last roommate sees the ad in the paper again, and determines to get to the bottom of the mystery.
