One Way Street plot
"A stolen fortune, a borrowed woman, and a man too many !"
Doc Matson (James Mason) is a physicist who has donated his knowledge to the local underworld. When the gang members return after a robbery, Matson suddenly sets a trap: he has poisoned the gang leader John Wheeler (Dan Duryea), and only an antidote in his possession can save him from certain death. In exchange for this antidote, the gang will have to give up the stolen $200,000. Fleeing possible reprisals, he also takes Wheeler's sweetheart Laura (Märta Torén) with him. Matson comes under intense pressure to such an extent that he begins to exhibit fatalistic personality disorders, driving Laura to despair. Finally, he finds peace by retreating to a small Mexican town to set up a hospital. But not for long: Wheeler is still after him. He soon decides to return to Los Angeles to return both Laura and the money to Wheeler. But will Wheeler be willing to do this?
