While the gang and Sheriff Bronson Stone are chasing the Piranha-Goat, the ghost of Crystal Cove’s best sheriff Iron Will Williamson (nicknamed Dead Justice) comes back from his grave to make Sheriff Stone quit his job. Dead Justice is trapping Crystal Cove’s top criminals, including the Piranha-Goat, making Sheriff Stone look bad. The gang eventually captures Dead Justice and solves the mystery. Fred asks his dad if he is proud of him for solving the mystery, but Mayor Jones answers no. Fred and Daphne then go to the Clam Cabin and Fred explains how Daphne is the only one who really understands him. He then asks her to marry him after the end of high school. Daphne agrees, and they share their first kiss together.
