While rafting in the Bluefish River area, four college kids are attacked by the mutant cannibal Three Finger. Only the teenager Alex succeeds in escaping through the woods. Meanwhile, a group of dangerous criminals are transported from the West Virginia Grafton in a custody bus escorted by three guards through the backwoods. When they park in a stop in a police station, Sheriff Carver is informed about the missing teenagers. The bus driver heads to their destination with the guards and the prisoners but a tow truck driven by Three Finger hits that bus that falls off the road. They are attacked by Three Finger and the perilous dominates the guards and the other plus prisoners. When they accidentally meet Alex, the girl tells how sick and threatening Three Finger is; soon Alex is telling the truth.—Claudio Carval / Chase midwest (US)
