In New Orleans, an illegal immigrant feels sick and leaves a poker game while winning the smalltime criminal Blackie (Walter Jack Palance). He is chased by Blackie and his men Raymond Fitch (Zero Mostel) and Poldi (Guy Thomajan), killed by Blackie and his body is dumped in the sea. During the autopsy, the family man Lieutenant Commander Dr. Clinton Reed (Richard Widmark) of the U.S. Public Health Service finds that the dead man had pneumonic plague caused by rats and he needs to find who had any type of contact with the man within forty-eight hours to avoid an epidemic. The City Mayor assigns the skeptical Captain Tom Warren (Paul Douglas) to help Dr. Clint to find the killers that are infected with the plague and inoculate them.<br /><br />"Panic in the Streets" discloses a simple story, but it is still effective and with a great villain. The engaging plot has not become dated after fifty-seven years. Jack Palance performs a despicable scum in his debut, and the camera work while he tries to escape with Zero Mostel is still very impressive. My vote is seven.<br /><br />Title (Brazil): "Pânico nas Ruas" ("Panic in the Streets")
