Body Puzzle tells the tragic and increasingly morbid story of the lovely widow Tracy (Gorky Park's Joanna Pacula). Not only has her famous pianist husband Abe died in an auto accident, but someone keeps breaking into her house and leaving severed body parts lying around. The investigating police officer, Michael (The Church's Tomas Arana), strikes up a hot and heavy romance with her to keep Tracy's mind off the rapidly accumulating trophies. The police chief (spaghetti western pro Gianni Garko) tells Michael to keep his mind on his job; soon he closes in on the one responsible for the killings. The clincher is the mysterious link between all of the victims.
