"Kabuto is a highly skilled assassin eager to escape his dangerous profession and the hold his handler, the sinister Doctor, has over him. The Doctor, a real physician who hands over Kabuto's targets as 'prescriptions' in his regular appointments with him, doesn't want to lose Kabuto as a profitable asset, but he agrees to let him pay his way out of his employment with a few last jobs. But the most lucrative jobs involve taking out other professional assassins, and Kabuto's final assignment puts him and his family, who have no idea about his double life, in danger.--
