This is a mid-1930s exploitation movie designed to "warn" good Christian girls and boys about the dangers of drinking, dancing, and premarital sex. For the 1930s these were indeed scandalous topics which today seem mundane. Ann, our central character, is corrupted by her fun-loving friend Eve. Eve introduces Ann to the evils of romance novels, smoking, dancing with boys and sneaking snorts of Daddy's brandy. Ann and Eve progress to dating men who are old enough to be their fathers. Finally the girls are caught at a drunken pool party where they are arrested and taken to the police station. While there, they are examined by a doctor (presumably for STDs) and given small cards identifying them by name as "sex delinquents"! Things go from bad to worse for poor Ann...
Wow a card identifying the girls as "sex delinquents" merely for attending a drunken pool party! Ann in particular wasn't even drunk and was still fully clothed at the party - no matter, the cops bust her too as a sex delinquent. I wish I had a card identifying ME as a "sex delinquent"... what a conversation piece that would be!
