Kevin McCallister is now grown up with his own kids. When he and his wife go out of town they ask their 77 year old crotchety neighbour Mrs Gibb to babysit. After Mrs Gibb suffers a heart attack, 15 year old Emma (who looks much older) masquerades as their replacement babysitter in front of the authorities. Now the kids have a whole week with no parents to tell them what to do, everything’s going great until Garry (Harry’s son) and Merv (Marv’s son) start hitting houses on their street, now they must band together to protect their home from the intruders.
