Harrison Grieve is an ex-biker who met the love of his life and changed his bad boy ways. After his wife is murdered, Harrison spirals into a plot to kill him and everything he holds dear as local law enforcement, CIA, FBI and his old biker gang turn on him. Atop the one remnant from his past, a Harley Davidson roadster, Harrison evades his pursuers while trying to unravel the mystery before him. Aramis Sickert is a genetic scientist who wields power at the highest levels of government. Upon finding out that his son was not really his, but rather a product of a lower form of DNA named Harrison Grieve, he goes insane with rage. Aramis quickly uses all his influence to bring death to the man who spoiled his genetically perfect family. With FBI agents, Jason Travis and Bill Smith in pursuit, and the head of the CIA bending to the dark secret that Aramis holds over him, Harrison races to unlock the reason for his wife's murder and bring his brand of justice to the man responsible.
