Boston P.I. Sunny Randall joins forces with her father to crack a 30-year-old case.

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 who headed the original task force: Phil Randall. Now retired, Phil calls on his daughter, Sunny, to help trap the criminal who eluded him so many years before. After interviewing only a handful of suspects, Sunny's instincts tell her she's found the killer, but she lacks the evidence needed for arrest. When he strikes twice more, Sunny decides to create a trap to catch him, and a compelling game of cat-and-mouse begins.
