After Fred goes on a crazed trapping spree which ends in police intervention, the gang decides he needs a long rest, so they take him up to Daphne’s beach cabin. Unfortunately, at that same time, a mythological shark monster named Dorsal Foot comes up on land and begins terrorizing the beach. The gang attempts to keep this from Fred, but the task becomes excessively difficult when Fred becomes suspicious and paranoid of everyone around him.
