Come On, Marines! 1934

"Lucky" Davis, a ladies-man and a devil-may-care U. S. Marine Sergeant, is leading a Marine-squadron on an expedition through a Phillipine jungle where an outlaw bandit is leading a guerilla-war rebellion. Their assignment is to rescue a group of children from an island mission that has been cut off from all communication. It comes as a bit of a surprise when Davis discovers that the "children" are a group of 18-25 year-old girls blissfully bathing in a pool while awaiting rescue.
