Relentless 3

Los Angeles detective Sam Dietz (Leo Rossi) is back and on the trail of another serial killer (William Forsythe) -- a misogynistic psychopath who's been coldly carving up the remains of his female victims and mailing the pieces to police. Dietz consults officers on the gruesome case, but when his girlfriend becomes the murderer's prey, he joins the urgent hunt for the killer in this pulse-pounding third installment of the action-thriller franchise.
