At the end of the last day of filming, one of the studio drivers loses the last can of film. The producer orders his assistant Joe Blake to contact all five extras involved in the last scene and make sure they are available next morning for retakes. Joe knows all five extras - Steven Marlow, ex-Commando officer, Barney West, a broken-down prize fighter, Mr. and Mrs. Bliss, 40 years in the profession and now retiring, and Toni Howard, a society girl bored with society. As he visits each in turn he has a glimpse into their various private lives, finding comedy, drama and tragedy.
