Derby Day is a typically British omnibus feature, delineating the fates of several different people during a single day at the racetrack. Peter Graves (not the American actor of the same name) plays a superficial movie star who has been won in a fan-magazine raffle by housemaid Suzanne Cloutier. Michael Wilding and Anna Neagle play a pair of disconsolates who have recently lost their respective mates in a plane crash. And Googie Withers and John McCallum (who were married in real life) portray a furtive couple whose horrible secret is revealed when they head to the window to collect their winnings. Though we count at least six principle characters in Derby Day, the film was released in the US as Four Against Fate.
