When a wealthy, lonely university music student is beaten and has his apartment trashed by a fellow dorm resident-bully and his gang, he goes mad, lures the bully into his room on pretense of forgiveness, slips him a paralyzing agent in a drink, throws him in a trunk and locks him in, and taunts the bully with the promise that he will be buried alive in the trunk. Only, once he gets his trunk and his prey to his country estate, the vengeful victim finds things keep going wrong...
