When DNA evidence reveals the wrong man has been serving time for the 1986 murder of a beautiful 15-year-old girl (Mae Whitman), Rush and Valens re-open the case and discover that the girl was the object of affection for several young and older men.

The investigation initially leads to Mark Adams, Eve's former boyfriend. Though Mark professes his innocence and is eventually dismissed as a suspect, he's clearly still in love with Eve and has an immediate connection with Lilly, who bears a striking resemblance to the dead girl. After speaking with Eve's mother and several of her old friends, the detectives find out crucial information about Eve's final days, leading them closer to finding the person who may have killed her.
