Californication (2007)

Season 5: Episode 6

When Samurai Apocalypse hits a lyrical roadblock with his protege, he calls on the best writer he knows: Hank Moody, who unites with Kali to imbibe, bear his soul, and write a song that takes Hank back in time to an era when he, Karen and Charlie were happier and life was simpler before "A Crazy Little Thing Called Love." But the present comes roaring back when Karen shows up at Hank's door, worried that she made a mistake.
