Jack eventually got caught by a small town sheriff who arrested him when he got back from taking a leak on the side of the road. Jack just gives up and goes off to be executed. I swear to you, that's what is written on the side of the truck. State Executional Transfer Vehicle. Just like that.
Somebody needs to hit the prop people over the head with a dictionary.
Jack somehow gets free of his cuffs and chokes out the guard in the back. The driver and his buddy in the front get a little worried, so they call back to their colleague. Jack reassures them that everything is all right, and they sigh with relief. Man, they deserve whatever they get. The State Executional Transfer Vehicle has an accident, of course, as it collides with a big tanker truck or something.
