A police officer stationed on the beach then stops by the condo, and is killed when Big Ed decapitates him with an axe.The others return to the condo, and as his friends get ready for bed, Ralph searches for Mike and Linda, and is killed when Big Ed impales him through the throat with a pitchfork. When Ralph does not return, Sue goes looking for him, and is caught by Big Ed, who stabs her in the crotch with a fishing gaff, and chops her head off. Ed and Pam find Sues mutilated remains, and the bodies of the other victims, in the basement, and are attacked by Big Ed. The two incapacitate Big Ed and try to drive away, but Big Ed jumps onto the car, and tries attacking them through the roof. Pam puts the car into reverse, and backs into a wall, crushing Big Ed into it, and cutting him in half at the waist. When a police car arrives, one of the deputies goes to inspect Big Eds body, and has his legs sliced off when Big Ed springs to life. As Ed and Pam look on in horror, Big Ed dies laughing maniacally. ........
