We meet Mitch Yost once a legendary surfer, but now a lonely figure. He has a son Butchie who used to be extraordinary surfer, but now a drug addict junkie, and a 13-year-old grandson Shaun, who may be the next big surfer. As Mitch rinses off by his station wagon; he levitates, and thinks he's having a hallucination. A stranger named John arrives at the Snug Harbor Motel; police arrest Cissy for getting snippy with a megastore employee; Shaun and Bill take a detour on the way to a surfing event.

Linc tries to infiltrate the Yost inner circle; Barry has a change of heart about the fate of the motel; Shaun has unexpected results when he takes part in a surfing competition; a greasy drug dealer named Steady Freddy arrives to harass Butchie, but changes his tune when bad news arrives, and John claims he's from Cincinnati.

Dr. Smith believes a paranormal phenomenon has occurred within the Yost family; Kai takes John to her trailer; and Cass comforts Mitch, unaware of her connection to Linc.

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

Bill gets a strange mandate from Zippy; and Tina lets the Yost family know that she is back in town.

Butchie puts together a reunion between Shaun and Tina; and John helps Bill and Cissy face their pasts.

Linc's Stinkweed reign is challenged; Dwayne eyes Shaun's online future; Dr. Smith tends to Palaka.

The locals in Imperial Beach worry about Shaun after a cryptic warning from John.

In the first-season finale, Butchie and Kai have a joyous revelation; and Imperial Beach plays host to a makeshift parade.
