In Arizona, when the Deputy Daniel "Dan" Saxon is fired after an argument with the corrupt Sheriff, he is recruited by the agent of the General Attorney Office Conroy Price to work undercover in the bike gang Jackals. He befriends the mechanic Virgil that introduces him to the Jackals' leader Blood using the alias Sid. He also has a love affair with the photographer Renee that recognizes him. Now Sid has to be prepared to cross the thin line between the law and outlaw to convince Blood that he is a drug and dealer biker.
