In Gila Junction, Arizona Jessica Fletcher is visiting her friend Norma Shey when the local Sheriff, Spencer, receives a call saying they've found Norma's SUV in a ditch with no one inside. She's okay but it's clear that someone took a shot at her, blowing out a tire. Norma has been doing research on a possible cover-up at an old military base and suspects someone is trying to silence her. Spencer soon has a murder to solve when Whitey Deaver is shot. There have been a number of armed robberies in the area by someone dubbed the truck stop bandit and Tiny Kerns may have found the thief's loot. Jessica thinks she knows who the truck stop bandit is but someone else killed Whitey.
