Help me identify this movie: A future setting, where suicide has been legalized. A construction worker/single father has a very sick son who is in the hospital. The father agrees to sell his body to a medical/scientific organization of some sort. He receives one million dollars and one year until his death date. He goes to the hospital to pay them, and is told his son has died. In the end, his son is actually alive and being held secretly because of something in his blood? That is deemed very valuable. The father has it, too, so he was coerced into believing he needed the money desperately so that he would sign the suicide agreement with this company. What's it called?
