This is the story of three gentle persons: Paul Rivers (Penn) an ailing mathematician lovelessly married to an English emigré (Gainsbourg), Christina Peck, an upper-middle-class suburban housewife, happily married and mother of two little girls, and Jack Jordan (Del Toro), an ex-convict who has found in his Christian faith the strength to raise a family. They will be brought together by a terrible accident that will change their lives. By the final frame, none of them will be the same as they will learn harsh truths about love, faith, courage, desire and guilt, and how chance can change our worlds irretrievably, forever.

Set almost entirely in London, England during five frantic weeks before Christmas follows a web-like pattern of inter-related, loosely related and unrelated stories of a dozen or more various individuals with their love lives, or lack of them.

The prime minister’s older sister Karen slowly grows aware of her husband Harry’s flirtation with an office worker named Mia.

Meanwhile, Jamie is another writer who leaves his girlfriend after catching her cheating on him and travels to France to write a novel where he pursues a possible romance with his non-English speaking Portuguese maid Aurelia. Also, Harry’s American secretary Sarah questions a romance she pursues with the office hunk Karl, but her personal family problems get in the way. Other secondary characters involve a photographer who pursues his best friend’s new wife Juliet; a pair of movie stand-ins, named John and Judy, who grow closer after their simulated love scenes; a libidinous chum who wants to travel to Wisconsin, USA to score with women; and a burned-out former rock star named Billy Mack who is the main connection between all stories involved.
