When a serial murderer dubbed “The Spare Change Killer” by the Boston press surfaces after three decades in hiding, the police immediately seek out the cop, now retired, who headed the original task force: Phil Randall. As a sharp-eyed investigator and a doting parent («You're smart. You're tough. You, too, are a paradigm of law enforcement perfection, and you're my kid”), Phil calls on his daughter, Sunny, to help catch the criminal who eluded him so many years before. Sunny is certain that she's found her man after interviewing just a handful of suspects. Though she has no evidence against Bob Johnson, she trusts her intuition. And she knows the power she has over him — she can feel the skittishness and sexual tension that he radiates when he's around her — but persuading her father and the rest of the task force is a different story.
When the killer strikes a second and third time, the murders take a macabre turn, as the victims each eerily resemble Sunny. While her father pressures her to drop the case, Sunny's need to create a trap to nab her killer grows. In a compelling game of cat-and-mouse, Sunny uses all her skills to draw out her prey, realizing too late that she's setting herself up to become the next victim.
