Radio Cab Murder is a 1954 British crime film directed by Vernon Sewell.
After serving a term in prison for safe-cracking, World War Two veteran and ex-con Fred Martin finds work as a taxi cab driver. He is engaged to be married to Myra, the cab company’s dispatcher, a former member of the Women’s Royal Naval Service. While picking up a fare, Martin witnesses a bank robbery and tails the criminals, but his cab is wrecked during the chase. The police find a well-known safe-cracker dead of apparent natural causes and ask Martin to go undercover, join the bank-robbery gang, and expose its leader.
