Years after his unforgettable childhood adventures, Kevin McCallister is now a 30-something tech-savvy entrepreneur living in New York City. Though he’s outgrown booby traps and burglars, the holiday spirit still lives in him—along with memories of family chaos.
When his family invites him back to Chicago for Christmas at the old house, Kevin hesitates, unsure if he’s ready to reconnect with the past he once fought so hard to survive… alone.
Back home, things are more chaotic than ever. His parents are separated again, Buzz is now a cop with a skeptical attitude, and the younger cousins are glued to their screens. But when a new pair of high-tech burglars plot to rob the neighborhood during the holidays—using drones and smart home hacking—Kevin finds himself in familiar territory: being the only one who sees the danger coming.
When the thieves strike, thinking the house will be empty, Kevin decides to stay behind, this time willingly. Armed with years of adult experience, a ridiculous amount of smart gadgets, and his legendary creativity, Kevin sets out to defend the house once again. But instead of toy cars and paint cans, he uses updated tools: hacked alarms, motion-activated projectors, and voice-controlled chaos.
As the traps escalate and the burglars unravel, Kevin also re-learns the true meaning of family. He bonds with his young nephew, teaching him how to be clever and brave—while also discovering how much he missed having people close. The night turns into a hilarious and heartfelt battle that brings the family together in the most unexpected way.
Home Alone 4: Kevin’s Return is a fun, modern twist on a holiday classic. Packed with nostalgic callbacks, fresh laughs, and clever updates, it reminds viewers that while the world (and the tech) may change, the heart of the holidays—love, connection, and a bit of chaos—stays the same. Kevin may be grown up, but some things… you never outgrow.
