While the rest of his family sleeps, a young man (Andrew 'Melvin' Weathers ) is viciously stabbed and killed in his own bedroom. The murderer slips out of the house and into the night - unaware that a 13-year old girl has seen him - and for years the murder will haunt Melissa Kountz, the young girl who witnessed her cousin's killer. The 1983 case grows cold, but in 2012, a veteran homicide detective finds clues and ultimately solves the mystery.
