Ten years later, most of the Party Down catering team have moved on, including actor/bartender Henry Pollard (Adam Scott). After a surprise reunion, the gang find themselves once again stoically enduring the procession of random parties and oddball guests all over Los Angeles.

Scott reprises his role alongside original cast members Ken Marino, Jane Lynch, Martin Starr, Ryan Hansen and Megan Mullally. They are joined by new cast members Jennifer Garner, Tyrel Jackson Williams, Zoë Chao, James Marsden and many more.
