A character study of a family on vacation. The emotional abyss and problems are behind the seemingly nice facade of an intact family as they experience guilt, love, and jealousy.

Eight very different couples deal with their love lives in various loosely interrelated tales all set during a frantic month before Christmas in London.

After two American prisoners are killed by guards in the act of escaping from a German POW camp in World War II, barracks black marketeer J.J. Sefton is suspected of being an informer.

Eight-year-old Kevin McCallister makes the most of the situation after his family unwittingly leaves him behind when they go on Christmas vacation. When thieves try to break into his home, he puts up a fight like no other.

Instead of flying to Florida with his folks, Kevin ends up alone in New York, where he gets a hotel room with his dad's credit card—despite problems from a clerk and meddling bellboy. But when Kevin runs into his old nemeses, the Wet Bandits, he's determined to foil their plans to rob a toy store on Christmas Eve.
