Tread Softly Stranger

Tread Softly Stranger is a 1958 British crime drama directed by Gordon Parry and starring Diana Dors, George Baker and Terence Morgan. The film was shot in blackandwhite in film noir style, and its setting in a gritty working industrial town in northern England mirrors the kitchen sink realism movement coming into vogue in English drama and film at the time. The screenplay was adapted from the 1953 stage play Blind Alley by Jack Popplewell.

Calico comes up with a plan for the brothers to rob the payroll at Daves workplace to steal enough money to cover Daves fraud and Johnnys debts. However at the arranged time Johnny is delayed in getting to the rendezvous, and Dave decides to go ahead with the robbery on his own. Johnny arrives at the mill just as Dave is leaving with thousands of pounds, but they are disturbed by the elderly nightwatchman and there is a struggle in which Dave shoots and kills him.Initially the police can find no leads as to the perpetrators of the murder, but the nightwatchmans son Patrick Allen is certain that the robbery was an inside job and his suspicions lead him to Dave when he tracks down a blind witness who heard the killing. The police enquiries finally lead them to Johnny, who is arrested and taken away for questioning. The nightwatchmans son then confronts Dave with his evidence, not revealing that his witness is blind, and convinces him to confess his own guilt. ........
