Amidst his parents' impending divorce, Kevin McCallister must foil his old nemesis Marv and his wife Vera's plot to kidnap a Crown Prince despite opposition from his dad Peter, Peter's fiancee Natalie, and Natalie's butler Mr. Prescott in Home Alone 4: Taking Back The House.

Caught in the middle of his parents' impending divorce, the now-nine-year-old Kevin McCallister reluctantly accepts to spend Christmas with his dad's affluent new girlfriend, Natalie, at her lavish mansion crammed with the latest hi-tech gadgets.

Once more, Kevin will find himself home alone and neck-deep in trouble when Marv--the remaining member of the notorious Wet/Sticky Bandits in Home Alone (1990) and Home Alone 2: Lost in New York (1992)--and his equally maladroit sidekick wife, Vera, cross paths with him, intent on pulling off the ultimate Yuletide heist. However, Kevin is already an expert in thief psychology, and, this time, the house is bigger and the crime-fighting equipment is more sophisticated.

Will things work out between Kevin's parents? Under those circumstances, can he take back the house?
