When Homer and Bart spend the day doing chores there's bound to be some fireworks - literally. Fixing Lisa's VCR with firecrackers backfires and the two are forced to make it up to her with a trip to the Festival of Books. At the festival Krusty is signing his new memoirs. And who is waiting for a signature but his long lost daughter, Sophie, the product of a Gulf War romantic liaison. Sophie wants to have Krusty in her life, but Krusty isn't so sure. When their day at the beach is no day at the beach, Krusty enlists Homer as his mentor in fatherhood. No wonder they end up nearly getting killed by the mob.
