William Fairchild directs this 1950s British comedy starring Richard Basehart, Simone Simon, George Baker, Sid James and Joan Hickson. Disaster strikes during the filming of a movie when the final reel of film is misplaced, leaving the production without an ending. Assistant Producer Joe Blake (Basehart) is sent out to relocate the movie's extras, who are now required for an additional day of filming. This proves tougher than expected since the private lives of the extras, who include disillusioned society girl Toni Howard (Josephine Griffin) and struggling boxer Barney West (James), are arguably as colourful as any onscreen role. Will Joe succeed?
