Izzy has enough problems of his own in everyday life, but of course, with his awful luck, he gets to take on a ton more trouble. Mysterious circumstances give him an unbreakable skin and great strength overnight, leaving him pretty much invulnerable. But he isn't the only one who suddenly changes. Izzy has to get to the bottom of it all, while at the same time trying to keep up with everything in his usual life and try to do some good, or feel the guilt and responsibility of not helping when he can.
