In 23 Paces to Baker Street, Philip Hannon is a successful playwright who lost his sight in a car accident. One day, while sitting in a pub, he overhears a group of men discussing the kidnapping of a young boy for ransom. Unable to see the men, Hannon can only hear bits and pieces of the conversation, but he realizes that the kidnappers are planning to meet in Baker Street.
When Hannon goes to the police with his information, they dismiss him as a crank, thinking that a blind man cannot possibly have heard what he claims to have heard. Frustrated and determined to help the kidnapped child, Hannon enlists the help of his loyal butler, Bob, and his ex-fiancée Jean Lennox, who is now a successful actress.
Together, the three of them set off on a thrilling journey through London as they try to piece together the clues and track down the kidnappers. Hannon's heightened sense of hearing and Bob's street smarts prove to be valuable assets as they navigate the dangerous underworld of London's criminal gangs.
As they get closer to the truth, they realize that the kidnappers are watching them closely and that their own lives are in danger. In a dramatic climax, Hannon must use all of his resources to outsmart the kidnappers and save the kidnapped child before it's too late.
23 Paces to Baker Street is a gripping thriller with plenty of twists and turns that will keep audiences on the edge of their seats. The movie is notable for its strong performances, particularly by Van Johnson as Hannon, and for its realistic portrayal of blindness and the blind man's reliance on his other senses to navigate the world.
