After a night of drinking, four college friends happen upon a woman all four know who has been raped and left for dead. When the woman does in fact die, the four friends are all questioned as suspects, but released for lack of evidence. A quarter of a century later, the police reopen the investigation in the hopes that the dramatic improvements in forensic detection will help crack the case, and the four friends slowly find their lives, both in the past and in the present, meticulously deconstructed and laid bare.
