A very slight tale based on an original American story by Leon Ware centered on the Golden Gate Bridge in San Francisco. This adaptation is set on the Tower Bridge in London. A little boy named Tommy watches as his father is arrested after a bad brawl. Tommy believes his father must have killed someone and rather than return home, he heads to Tower Bridge to set up housekeeping there. The atmosphere and life around the bridge are a secondary protagonist in the story, introducing several interesting characters.
