A career criminal informs Iowa police that his gardener has asked him to murder a young family. Police initially doubt the story but when their undercover officer can make the case, the former landscaper picks 3 new targets from behind prison walls.

A woman goes to the police when she's contacted by a professional drummer to kill his partner but it's unclear if the target is the man's wife or his mistress. Will the police figure it out in time to save her?
