Scotland Yard Inspector George Gideon starts his day off on the wrong foot when he gets a traffic-violation ticket from a young police officer. From there, his 'typical day" consists in learning that one of his most-trusted detectives has accepted bribes; hunts an escaped maniac who has murdered a girl; tracks a young girl suspected of involvement in a payroll robbery and then helps break up a bank robbery.
