Death is natural. Murder isn't. Mercy loves her job. Traveling is the fun part. New coworkers aren't. She thinks she knows what's in store for her at a Nebraska nursing home. But within hours of her arrival, a man is dead, and she's in way over her head. Sheriff Charlie Wagner is a no-nonsense guy. When he's called to investigate a suspicious death, it doesn't take long to figure out the situation is anything but ordinary, including the chatty, quick-tempered traveling nurse. He needs to find the murderer. She needs to prove her innocence.
