In the film, government agents are besieged by the ghosts of a massacred chain gang while driving down a desert highway.

He reveals that he and Steph are Federal Marshals assigned to capture Rabbit and bring him to court in Los Angeles to testify against his former boss, a mobster named Benny "The Buzzsaw" Buffalino, who has recently become partners with the Russian Mafia.

Jack calls for a Suburban driven by four other marshals to pick them up before Sergei and his crew of killers arrive with heavy firepower.

They leave out the back and battle the assassins until marshals; Nick, Mary, P.T., and Joe arrive between them.

He reads that a second highway exists next to Route 66, leading faster to the California border.

Hearing the story, Jack has strange quick flashbacks of four prisoners digging a hole surrounded by law enforcement.

The marshals arrive at a deserted tourist attraction bordering Route 666 and see a restricted access sign.

As Jack debates about using the road, he experiences more flashbacks and tells Stephanie that he was born around the area and his mother died when he was six, and he hardly knew his father.

La Roca was a bank robber who quit robbing after marrying a woman in a small town and having a baby, Jack.

After six years, there was no more money for his family, so he tried to rob a bank but was caught and thrown in the same prison as Hackman, Slater, and Pikowski.

Blood rushes out of Sergei's back, attracting the decomposed walking corpses of Slater, La Roca, Pikowski, and Hackman.

While screaming at Nick and Mary to get out of the Suburban, Rabbit takes the silencer off the gun and fires at the zombies, alerting everyone else.

He travels along the road until he sees the two vehicles with their tires melted at a ruined drive-in theatre and reunites with the rest of the group.

The group goes to check in on Nick while Rabbit stays handcuffed to a pole and stomps a Scorpion, exposing much blood.

After four hours of waiting, Jack has another flashback and sees his father, Slater, Hackman, and Pikowski working on a road.

Hackman pulls out a knife and attempts to escape while John hides under a machine and tries to stay away from the trouble.

The escape fails, and the unseen police officer in charge makes them start digging a large hole.

Though La Roca didn't assist in the attempted escape, he is knocked unconscious and thrown into the hole dug by the three others.

Conaway and his men open fire at the convicts in their legs, keeping them alive and preventing them from moving out of the hole.

After seconds, John suddenly snaps and pushes the jackhammer into Slater's stomach, destroying his spirit and body.

John walks onto the dirt and crosses the afterlife into Heaven, finally lifting the curse on Route 666.

He falls barely stable to the ground and has an unseen vision of an even larger steam roller (as the Grim Reaper) coming towards him.

Jack, Steph, and Rabbit walk underneath the sunset, knowing that the curse has finally lifted.
