Rick Rosner is obsessed with doing things right. If he does not get it exactly right the first time, he just does it again. He completed high school four times before he was satisfied, at the age of 34. To manage this he had to use a combination of disguises and false IDs. Now he is just as obsessed with the TV quiz show "Who Wants to be a Millionaire"?. He attended the show, but lost due to a trick question. On the brink of madness, he now watches every program again and again in the hope of a one in a million chance of correcting his error from the past.
