The Tape of Karma

Overview:

A gorehound named Marvin orders a lot of splatter movies for a movie marathon with his fellow gorehounds. He ends up ordering so much that he has trouble keeping up with orders. Come the day of the marathon, him and his friends watch gore and grime until very late at night. Just when they think the marathon is over, Marvin rediscovers one tape that he forgot all about... He quickly calls his buddies back over to watch it, and they soon discover that the tape is something far more ominous than they could have ever suspected.
