OK, it was about a military mental hospital, in which deserters etc were kept to ascertain whether they were actually mad or pretending to be to get discharged. then a new doctor turns up and allows them to sort of take over the asylum. It turns out toward the end that he is not the doctor that was supposed to come and is in fact a patient who was a renowned killer in the field attempting to redeem himself through doing somethig good. He saves this one guy who is an astronaut afraid that he will die in space (a common theme if you remeber from William Peter Blattys the exorcist ("You'll die up there.")) from a wierd ass group of bikers, by first humiliating himself by getting pissed on, but then as they are about to kill the other guy he kicks their asses severely but dies in doing so.
