The Radio Cab Murder despite a few holes in the plot is a fewer frills noir than even American films would have had back then from our B studios. Still the action is kept at a good pace and there's not much extraneous material getting in the way of the plot.
By one of those movie coincidences Jimmy Hanley an ex-convict now driving a cab tails a robbery/murder suspect in another cab, but Hanley loses them in a park. Right after that an anonymous letter is sent to his cab company asking them by what right to they put the public in danger by hiring an ex-convict.
The police think it's a set up of sorts and Hanley goes to work for them. He's contacted soon enough by the same gang who needs his skills as a safecracker.
There are way too many coincidences in this film's story for me to give it a top rating. Hanley is cast well as a British every man, he'd grown out of playing callow youths which he primarily did in the Forties. Best by far in the cast supporting him is Sonia Holm who plays a beautiful but deadly female who is part of the gang not just a moll for the leader. Lana Morris plays Hanley's girlfriend who is the cab dispatcher who is his lifeline and proves to be resourceful.
At one point a snitch is murdered and the cops can't find evidence of a homicide. I won't reveal how they did it because it's what almost happens to Hanley. But forensics even in 1954 should have figured it out.
Radio Cab Murder despite flaws is still entertaining enough.
