From the creator of Deadwood comes this new "surf noir" drama about a dysfunctional Southern California family galvanized by the sudden arrival of two strangers: a man out for revenge and a boy looking for surfing lessons. In Imperial Beach, California, the dysfunctional Yost family intersects with two new arrivals to the community: a dim-but-wealthy surfing enthusiast and man spurned by the Yosts years ago.
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.
Mitch seeks helps south of the border; Cissy organizes a search party to find Shaun; Bill loses a trusted source of information; and Palaka's gift ends up with an unintended recipient.
