Resuming immediately after the events of the previous film, medical teams come to clear up the carnage caused by Jason at Higgins Haven, which includes taking his corpse to the morgue. Problem is, he isn't dead and after a quick recovery, he heads back to (a new) camp to slaughter anybody who gets in his way.
Not bad, certainly watchable but by this fourth outing you do start to wonder where the series is heading. Don't be fooled by the misleading title either, another one, A New Beginning followed just one year later. ~ The Lord

Yeah, right, the Final Chapter...The films are becoming only interesting for the make-up effects. ~ The Sloth
