Donna takes pity on Ernie despite him being in a terminal state of confusion and the two become involved with each other. Later at a party, Ernie meets a former girlfriend, Gail, and the two resume their previous relationship. For Ernie life is a game, but as he moves between the two women, his fragile mental state declines and his imagined rejections drive him to fantastic and dangerous schemes.
