When Darcy, a lesbian woman, discovers a note she believes to be from her secret admirer slid under her door, she embarks on what becomes an increasingly wacky scavenger hunt. Being car-less, however, forces Darcy to recruit her best friend's boyfriend, Jack, as her driver. The enjoyably mismatched duo have discussions and debates as they drive to each new clue. They also pick up Jack's occasional Lyft clients, who provide some of the film's funniest moments.
