Baby-boomer Meggie Moore finds life in the small town of Pine Lake, Minnesota, a little too mundane even with her part-time job at a local gift shop. Always up for an adventure, Meggie accepts a housesitting position on Spirit Lake knowing full well there has been a rash of burglaries in that area. Shirley, Meggie's outspoken friend and side-kick, labels Meggie as a nut who has lost touch with reality and vehemently argues that the housesitting position would be extremely dangerous under the circumstances. The adventure at the lake takes a sinister turn when Meggie, along with Shirley, stumble on the body of a lake neighbor. They become suspects in the murder, do some investigating in order to clear their names, and risk their own lives in the process.
