John gets roughed up by some thugs; Kai connects with Butchie; Vietnam Joe brings Dr. Smith a new patient; Shaun's adult-film-star mother Tina arrives in Imperial Beach.

Bill is "conveyed" a strange mission from Zippy; Shaun's mother Tina lets the Yost family know she has returned to town.

Butchie orchestrates a reunion between Shaun and Tina; John helps Bill and Cissy face up to their pasts.

Linc's Stinkweed reign is challenged; Dwayne eyes Shaun's online future; Dr. Smith tends to an ailing Palaka; Ramon supervises the building of a shuffleboard court.

An ominous message from John strikes fear for Shaun's safety into the hearts of Imperial Beach denizens.

Attempting to conjure some courage, Mitch tracks down a reclusive 'chemist' in Mexico; Cissy heads up a citywide search team; Bill loses his feathered medium; Palaka's good-luck gift to Freddy ends up with Barry.

Butchie and Kai wake up to a joyous revelation; Imperial Beach plays host to a makeshift parade organized by a revamped Stinkweed.
