The Graveyard by Michael Feifer

4.20

Six friends go to the Placid Pines Cemetery to play hide and seek in the tombs. When a "harmless" prank ends in the accidental death of one of the group, the prankster goes to prison. Five years later the friends meet up in the cemetery again to resolve the issues of that fatal night. When members of the group start getting murdered one at a time, they realize that this time it's no prank.
