Cobra (1986)

Criticised for his brutal and unconventional ways, hard-as-nails Lieutenant Cobra is the tip of the spear of LAPD's elite Zombie Squad. But crime runs rampant in the city. As a string of seemingly unconnected assaults on civilians drags the hardened officer into a violent war with the psychopaths of The New World, an underground cult aiming to weed out the weak, Cobra must escort key witness Ingrid to a safe house. However, the Night Slasher and the movement's delusional killers will stop at nothing to track her down. Now, there is no turning back--only one man stands in the way of the disease. Is the murderous cult prepared for swift justice and Cobra's deadly bite?
