When elderly Morey Gilbert is found lying dead in the grass by his wife, Lily, it's a tragedy, but it shouldn't have been a shock - old people die. But when she finds a bullet hole in his skull, the blood washed away by heavy rain, sadness turns to fear. It looks like an execution.

The slaying of an old couple in small-town America looks like a one-off act of brutal retribution. But at the same time, in Minneapolis, teams of detectives scramble to stop a serial killer striking again. When the two separate investigations converge, it seems an old killer has resurfaced.
