Joey, who is still taking medication to keep him from getting too wired, goes to spend the summer with the hard-drinking father he has never known and tries to help the baseball team he coaches win the championship.

Joey's father returns, calling himself Charles Heinz and apologizing for his past bad behavior, and he swears that once Joey and his mother change their names and help him fix up the old diner he has bought, their lives will change for the better.
