Grown up and eager to reconnect with his family, Rusty Griswold decides to recreate the disastrous road trip of his own childhood, loading his wife and two sons into a bizarre rental car for a cross-country haul to the legendary theme park Walley World. Predictably, every stop along the highway curdles into fresh humiliation and misadventure. A raucous, gleefully crude reboot of the Griswold saga that leans into gross-out gags and self-aware nods to the original, ferrying the beloved comedy franchise into a new and considerably ruder generation.
