What kind of maniacal deviant preys on young teenage girls and viciously terrorizes a small town in upstate New York? Roman Wolfe, a.k.a. Wolfman, is a Vietnam combat veteran who had specialized in the stealthy, nighttime-stalking and killing of the enemy. After the war Roman gets a college education and becomes an elementary school teacher who is still haunted by his violent war experiences on the "killing fields" and in the jungles of Vietnam. Roman feels the need to end his teaching career when his school's community is informed about his specialized actions in Vietnam and many parents react negatively. When most parents no longer want their children placed in Roman's classroom, he resigns his teaching position and becomes a Private Investigator who prefers to handle cases involving children. Shortly after becoming a PI, his two high-ranking state trooper friends ask him for help as a consultant in solving a serial murders case involving the killing of female children. Now Wolfman must emerge again to hunt a sadistic, but intelligent killer.
