A few years have passed and Hank is living in New York but looking for a ticket out of town after his latest breakup. He accepts an invitation from Charlie to come to Los Angeles for a job writing a film starring rapper/actor Samurai Apolcaypse, then reunites with Karen, her former professor and now-husband Richard, and his daughter Becca, who now has a boyfriend named Tyler that is the spitting image of Hank himself ... in the worst possible way.

Hank passes on writing Samurai Apocalypse's new movie but Sam won't take no for an answer and drags Hank to a meeting with director Peter Berg, where they discover that Hank and Peter have shared more than just a love of the written word. Sam takes it on himself to get rid of Tyler, which makes things worse between Hank and Becca. Co-parents Charlie, Marcy and Stu have their hands full when Little Stuart exposes himself to a preschool classmate, and Charlie takes it upon himself to mend fences with the offended girl's attractive mother.

Hank hands a completed draft of "Santa Monica Cop" over to Samurai Apocalypse, but he still finds himself stuck in L.A. when he's asked to take Kali, his "acquaintance" from the flight to Los Angles, out for a night on the town. Tyler crashes at Karen and Becca's house while he recovers from his injuries. Charlie is rescued from a serious parental crisis by Stuart's nanny, Lizzie.

On the first day of production on Hank Moody's latest movie "Santa Monica Cop," Stu has brought back his "F--king and Punching" director in hopes of creating a cinematic masterpiece, but Hank's rendezvous with the film's leading lady puts his relationship with Sam in jeopardy. Luckily for Hank, Stu and the production's crew, Charlie has a backup plan.

Hank discovers the bartender at a local watering hole is his late friend Lew Ashby and wonders if he's in Hell. Richard makes a startling announcement about Hank and Karen. Hank tries to make things right with Becca, but her news about Tyler leaves him stunned. On the set of "Santa Monica Cop," Sam's jealousy and fondness for firearms give Charlie an opportunity to show how much he loves his best friend and number-one client; Hank's arsonist ex-girlfriend surprises him with a way for them to be together forever.
