Finally paroled after serving 20 years in prison, he terrorizes the residents of his hometown by making chicken noises, crowing like a rooster and attacking people. He winds up at a farm run by a woman and her daughter, where he takes them captive and then starts killing off her neighbors. The mother realizes she and her daughter must escape before he kills them, too.
