An old, legendary killer is betrayed in the most brutal fashion... but instead of dying in the gutter, he wakes up young again. The only problem? Nobody recognizes him anymore. With a fresh, pristine body and decades of deadly, blood-soaked experience still sharp in his mind, he realizes he can climb back to the top of the underworld stronger and more dangerous than ever before. Killer Pietro is a fast paced, visceral action series overflowing with brutal, bone crunching fights, a cold dish of revenge, and the terrifying return of a monster the world thought it had long buried.
