Jack Jr. (Nick Corirossi), his reluctant co-captain Miles Jr. (Armen Weitzman), and the rest of the Napa Boys gang are back for one more wine-sloshed journey into the unknown. With a mission set forth by the mysterious "Sommelier,” they are joined this time by Puck, a bright young podcaster and the Napa Boys’ biggest fan, as the group embarks on the adventure of a lifetime. Featuring Sarah Ramos, Mike Mitchell, Chloe Cherry, Vanessa Chester, Paul Rust, Jamar Neighbors, Nelson Franklin, David Wain, Ray Wise, Riki Lindhome, Natasha Leggero, Ivy Wolk and Beth Dover, The Napa Boys enlists a hilarious ensemble of alt-comedians to hop in the Wine Wagon™ for the new installment in this historic (made-up) franchise.
