Hero and the Terror

Homicide detective Danny O'Brien (Norris) is known simply as "Hero" for having brought down L.A.'s most vicious serial killer: Simon Moon (O'Halloran), a.k.a. "The Terror." But for years, O'Brien has secretly been haunted by the fact that his capture of Moon was a fluke. When The Terror escapes from jail and returns to his old killing ways, O'Brien finally gets the chance to earn his glorified reputation if his monstrous enemy doesn't destroy him first!
