James Mason gets top billing in his first movie, playing an unscrupulous (shall we say, "too fervent") newspaper reporter who is on the trail of a cop killer. Alastair Sim is fun in a minor role as a fellow reporter. There are some parts that seem quite silly (& are unintentionally laughable) by today's standards, but the film has an exciting climax. There are several unexplained issues in the plot that are left dangling.
