Plot
Biker Cary Ford stops at a diner owned by his ex-girlfriend Shane. Later, Ford meets up with his best friends Dalton and Val. En route to a motorcycle party, they encounter the Reapers, a biker gang consisting of leader Trey and his brother Junior, who get into a scuffle with Ford.
At the party, Ford sees Shane, who is mad that he left. Biker gang the Hellions then pulls up. It includes leader Henry James, his girlfriend China and his right-hand man Luther. Henry is irate at Ford for stealing his bikes (which contain crystal meth). He gives Ford an ultimatum until sundown to return the bikes.
That night, Ford and his friends arrive at a nightclub where biker gangs hang out. The three gangs run into each other and cause a brawl. Scared, Junior runs into the bathroom to find the Hellions there. Junior apologizes to Henry for being unable to pay him back for a botched drug deal (which Trey refused to allow earlier) and begs Henry to give him time to work it out. Henry instead kills Junior. Ford, Shane and the two friends then spend the night at a motel.
At the murder scene, FBI agents Tehya Henderson and Jay McPherson assure Trey that they will find Junior's killer. China becomes a false witness and says that Ford killed Junior. Furious, Trey swears to kill Ford.
After learning that Ford is wanted for Junior's murder, Shane, Ford and company hit the road. The Reapers find them and a chase ensues with all riding into a forest. Ford tells his friends to split up, resulting in the chase being led near a passenger train. In the ensuing struggle, Trey falls in front of the train with his leg getting caught on the tracks. Ford saves Trey and gives him his own bike to escape, leaving Trey puzzled. Shane, Dalton, Val and Ford later find a cave to stay for the night.
Ford calls the FBI agents to tell them that he is innocent. McPherson picks up the phone and says that he does not believe Ford. However, Henderson does. The next morning, the four hitch a ride inside a truck, which is stopped by police checkpoint. Before the agents open the back of the truck, Ford and Shane bust out in a race car with the two friends on their bikes. The four drive onto a highway with the FBI and Trey on their tail.
Ford jumps onto Val's bike and tells him to ride with Shane. Trey and the two agents follow. The agents survive a crash where their Hummer hits a construction pipe. Trey rides his bike into Ford's, and the two crash. Holding Trey at gunpoint, Ford explains that he did not kill Junior. Trey asks who did it and Ford says that it was Henry and he set them both up. Trey agrees to partner with Ford as he sets up a meeting with the agents.
Ford calls Shane and orders his group to come and meet him and Trey at her garage. Subsequently, the agents bust in and tell Trey and Ford to get down. Henderson asks for an explanation, believing that Ford is innocent. As he tells them, McPherson shoots Henderson, apparently killing her. McPherson is Henry's mole in the agency and is working with the Hellions. Henry, China and Luther arrive with Dalton and Val in chains and Shane as a hostage. Ford says that Henry can take the bikes back. However, Henry wants to kill Ford and Trey (after admitting to Trey that he killed Junior).
Thereafter, a fight begins with Trey killing Luther. Henry and China leave the garage while Ford frees Shane and Trey unties Val and Dalton. Together, they leave the garage. Henderson (who was wearing a bullet proof vest) then blows up the garage, killing McPherson. Outside, China meets up with Shane. In the ensuing fight, Shane kills China.
Ford catches up with Henry in a bike chase. Henry shoots at Ford's bike, causing fuel to leak and ignite. Ford lands on top of Henry's bike as the fire catches up to them causing both bikes to explode; throwing Ford in the air and killing Henry. Shane picks him up and they return to the garage to find the others. Meanwhile, Henderson survived, but is injured.
Ford and Shane get back together and decide that the four need a vacation. Val picks up his girlfriend, and the five ride off in the desert.
