Alison "Allie" Jones is a software designer in New York City. While her professional star is on the rise, her personal life is a mess. Allie banishes her fiancé Sam Rawson from her rent-controlled apartment on Manhattan's Upper West Side, after discovering that he slept with his ex-wife. Allie finds platonic comfort in her neighbor Graham Knox, an aspiring actor with a sensitive shoulder to lean on. Realizing that the only way to hold on to her apartment is to find a roommate, Allie places an ad and interviews a succession of unsuitable candidates before settling on the shy Hedra "Hedy" Carlson, the ideal roomie in Allie's eyes. But the new lodger has a secret past which haunts her.
