Angelo Doyle lives two totally separate lives — fearsome NYC hitman and sleepy upstate Cooperstown photocopier salesman and father. Both of them are threatened when he is diagnosed with Alzheimer's, a disease he already lost his older brother to.

Roy Freeman, an ex-homicide detective with a fractured memory, is forced to revisit a case he can't remember. As a man's life hangs in the balance on death row, Freeman must piece together the brutal evidence from a decade-old murder investigation, uncovering a sinister web of buried secrets and betrayals linking to his past. With only instincts to trust, he faces a chilling truth - sometimes, it's best to let sleeping dogs lie.
