The Devil's 8

Federal agent Ray Faulkner (Christopher George) poses as a road gang convict and arranges the escape of a group of hardened chain-gang criminals, forcing them into a helicopter. He trains the men in high-speed driving and hurling lighted bombs at pinpoint targets, and they intercept the moonshiners' delivery cars until Burl (Ralph Meeker), the local crime boss, is forced to give Faulkner a share of the illegal whiskey operation.
