Forced by problems with the airplane to land in rural Mexico, for a time Matson and Laura establish a pleasant life and he is able to medically assist some of the villagers.

About to meet the same fate, Matson produces a gun and kills Ollie instead.

As they leave, Matson turns to go phone an airline to arrange his and Laura's return to Mexico, but he is hit by a car coming down the one-way street.

[2] Film critic Bosley Crowther dismissed the film as uninteresting, "Perhaps it is all the fault of the script, which has our hero vacillating between a life of crime and regeneration via a lady's love and an honest but unremunerative practice.

What it all adds up to is a standard romantic melodrama illustrating the facts that crime obviously doesn't pay and that the scenery and people below the border are colorful ... Like its title, One Way Street is explicitly obvious and not especially exciting.
