My Brother's Keeper (1995)

Identical twin brothers Bo and Tom Bradley are both well loved school teachers in the same Long Island school district. Together they are offered an opportunity for a bone marrow transplant from Bo to Tom, who is HIV positive, in order to stop the growth of Tom's HIV infection, or even to cure Tom all together. But just before the day of the surgery, Tom's insurance company refuses to cover the procedure, forcing Bo and Tom to sue the insurance company in a bid to save Tom's life.
