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.

A brutal mugging leaves Grey Trace paralyzed in the hospital and his beloved wife dead. A billionaire inventor soon offers Trace a cure — an artificial intelligence implant called STEM that will enhance his body. Now able to walk, Grey finds that he also has superhuman strength and agility — skills he uses to seek revenge against the thugs who destroyed his life.
