Much of this lively, low-budget British comedy is filmed in real-time as it chronicles the strange wedding day of upper-middle-class girl Samantha whose beautiful garden ceremony is abruptly interrupted by three Cockney jewel thieves on the run after their latest heist fell apart. While hiding out at the wedding the crooks get involved with the family. Things really go nuts when the chauffeur chokes on an hors d'ouvre and keels over.
