City of Fear on AllMovie

Fairly fast-paced, with only a lull here and there, this standard thriller by director Irving Lerner was one of his most successful films. It stars (Vince Edwards) as Vince, an escaped convict who grabs a metal vial from the prison's hospital before he makes his break. He thinks it is his ticket to the easy life because it contains heroin. Instead, the vial contains radioactive cobalt that could first sicken and then kill anyone who comes in close contact with it. The police are caught between the devil and the deep blue sea. If they publicly announce a vial of deadly cobalt is on the loose, in the hands of an escaped convict, they might touch off a stampede. On the other hand, if they keep it a secret, who knows how many people will die.
