In the 1980s Sheila Wysocki shared a college dorm room in Texas with a woman called Angela Samota. The pair became very close despite their personalities being very different. Then, in 1984, tragedy struck: Angela was raped and murdered. There were leads in the case, but eventually it went cold. Then, two decades after Angela's death, Sheila decided to become a private investigator to solve the case. But, would she be able to find the killer?
