TM 05637 was created to be a killer. Genetically engineered for superiority, he was facing a life of missions, blood, and death until his creator decides to set him free. On the run from those holding his leash, he is found by David Conley, an ordinary store owner who stumbles upon a remarkable find. Renaming himself "Tim," TM 05637 sets out to discover what it means to have a normal life.
Through his friendships with a young boy dealing with a nightmarish family life, and David's mother, who decides Tim is perfect for her son, Tim slowly discovers his humanity. Even more importantly, David teaches Tim about the power of love. But General Woodard, leader of the project that created Tim, threatens their happiness with his determination to bring his evasive quarry permanently to heel.
As the search net closes ever tighter around him, Tim must find a way to thwart his pursuers so he can stay with David and live out his dream.
