The spine chilling and bizarrely violent tale is of a man brought partially back to life by the blood of his brother.
Frank (Sean Chapman), is a sexual adventurer who is always on the search of new carnal pleasures. When he purchases a mysterious Chinese puzzle box while visiting an unnamed Third World country, his life changes forever!
Back home in England, he opens the box only to discover that he has unlocked the door to hell. Frank is pulled into another dimension, whose inhabitants, known as Cenobites, push him over the fine line between pleasure and pain by ripping him apart with tiny fish hooks.
Years later, Frank's brother, Larry (Andrew Robinson), moves his family into the house - to which, through some blood spilled on the attic floor, Frank returns in near-skeletal form. With the help of his sister-in-law Julia (Clare Higgins), who has always held a torch for the other brother - Frank begins sucking the life out of bodies that she has lured to him, in order to regenerate his new body to it's old form.
Meanwhile, Larry's daughter from a previous marriage, Kirsty (Ashley Laurence), begins to suspect her hated stepmother of having an affair, and to her horror becomes involved with Frank, the puzzle box and the Cenobites. Now she finds herself bargaining with the Cenobites, angels to some, demons to others, whose greatest pleasure is the greatest pain.
