This film is not in the league with "Sex Madness" and other exploitation films. Instead of trying to scare people away from a problem, it explained how to avoid or treat it. It is melodramatic, but well acted with good production. Tim Holt, Ward Bond and J. Carroll Naish appear as victims, and Lewis Milestone directed.(I image there were a lot of outtakes, though, when the actors couldn't help laughing when they had to say things like "I noticed a sore...down there.") I'm not old enough to remember syphilis--or patent medicine "doctors"--being a big problem, but I appreciate this film as a slice of the social history of our past.
