Two decades after unexpectedly becoming a father figure, Sonny Koufax is now a proud dad — and facing a whole new kind of chaos. Julian, the once wide-eyed kid he raised, is now a young adult navigating college, relationships, and identity. But when Julian unexpectedly drops out of school and returns home with a wild business idea, Sonny’s carefree lifestyle is thrown into disarray.
Determined to “parent better this time,” Sonny tries to reconnect with Julian by supporting his plan to start a bizarre pet-sitting startup. But their relationship is tested when Sonny’s immature habits begin clashing with Julian’s need for guidance — especially when Julian starts dating someone Sonny strongly disapproves of: a hyper-organized, no-nonsense lawyer with a mysterious past.
Things spiral when Sonny’s old friends, including Layla and his lazy buddy Phil, get involved in the business. With unpredictable animals, bizarre clients, and neighborhood chaos, the startup turns into a full-blown disaster. Meanwhile, Sonny secretly worries he’s become a “bad dad,” and begins to reflect on what it really means to grow up — even at 50.
Just when everything seems to be falling apart, a crisis forces Sonny and Julian to confront their differences. Through miscommunication, laughter, and a few heartfelt breakdowns, father and son must decide whether they’re stuck in old patterns or ready to build a future as real adults — and as family.
Big Daddy 2 is a hilarious and heartwarming story about second chances, unexpected responsibilities, and the messy beauty of modern fatherhood. With Adam Sandler’s signature mix of slapstick and sincerity, this sequel delivers laughs, lovable chaos, and the reminder that you’re never too old — or too young — to grow up a little.
