If you are a hardcore horror fan you will probably know. This movie was one of those movies like "the texas chainsaw massacre." The movie seems to be created in the mid 80's. There was a husband, wife, 10 year old boy, and a teen girl in a wheel chair. These diabolic people were former doctors and they created medicines and such. There were two men who harvested people for their organs. They killed the parents, and had the little boy rigged on this machine living because they took out some of his organs. They had the teen girl strapped to a bed and she couldn't walk because she was paralyzed from the waist down. Some how, these men created some kind of serum and injected it into her spine and she could walk.

What is the name of this movie?
