"Sometimes when I'm at work and waiting for customers I think about the two of us living like kings and not bothering about the future. Because there may not be any future to bother about, you know. Not for anybody, one of these days. And it's a wicked world."
Average couple Janet and Howard's lives begin to unravel when Howard's photographic memory helps win him a gameshow fortune. Janet doesn't want their lives to change that much. She's quite happy working at the supermarket, cooking for her husband three times a day and watching quiz shows in the evening.
But once Howard unleashes his photographic brain on the world, the once modest used-car salesman can't seem to stop. And what he sees as the logical conclusion to his success isn't something Janet can agree to.
