In 1980, Jamie Kellum kills college friend, Katherine Foster, in a fit of jealous rage. Two decades later, Kellum, now Jamie Letson, tells her AA sponsor of her crimes, leading police to make an arrest in a 20 year old case. The body of Katherine Foster is discovered at the University of Alabama. A student reports hearing gunshots the night before she was found, leading police to conclude that Foster was shot and left in the woods. Suspicion falls on a campus security guard, an apparent suicide who was obsessed with Foster's murder. The guard is cleared and the case goes cold for two decades before a whispered confession to an AA sponsor leads police to arrest and convict Jamie Letson, a friend of Katherine's.
