Friday the 13th Part 2

A fresh batch of teenage camp counselors return to the ill-fated Camp Crystal Lake five years after its most recent atrocities. Since the apparent perpetrator of those crimes was decapitated by the only survivor, the plucky teens ignorantly go about the business of reviving the camp, unaware that they are being stalked by an unseen figure who lives in the woods, waiting for the right opportunity to take bloody revenge.
