Twenty-five years after reluctantly raising a kid who wasn’t his, Sonny Koufax (Adam Sandler) is now a semi-responsible adult with a law career and a comfortable, if slightly chaotic, life. But just when he thinks his wild parenting days are behind him, Julian (now in his 30s) shows up on his doorstep — stressed, newly single, and dragging along his own 7-year-old son. Completely overwhelmed by fatherhood, Julian turns to the one guy who accidentally taught him everything: Sonny.
As Sonny tries to coach Julian through the ups and downs of modern parenting, he’s also forced to confront his own lingering immaturity, aging insecurities, and maybe even a few secrets of his own. With messy custody battles, PTA disasters, and heartfelt late-night talks, Big Daddy 2 is a comedy about second chances, evolving families, and proving that you’re never too old to grow up — again.
