The Party Down crew caters an exclusive backstage launch party for a young, wildly eccentric pop star named Jackal Onassis (guest star J.K. Simmons). As the star’s bizarre demands escalate — including a private bowl of only purple M&Ms and a “silent cheering” section — Roman tries to pitch him a sci-fi screenplay, Henry deals with an ex-girlfriend now working as Jackal’s handler, and Kyle attempts to become the singer’s new best friend. Meanwhile, Constance bonds with Jackal’s pet snake, and Ron struggles to keep the gig from spiraling into chaos. approx
