Traffic In Souls

A country girl, just into the big city, is misled from the train station to a 'den of iniquity' where she is held captive. Two immigrant girls, literally fresh off the boat, are promised 'good positions and salary' but instead are trapped in that same den. A naive city girl falls for a smooth operator who drugs her drink then carries her off to another den. All the work of one mob, and a high society elite who is, literally, 'the man higher up' - his office is upstairs from the mob's. This mob doesn't look tough, but they go out like gangsters - almost 20 years before "Little Caesar" and "Scarface". And although we're supposed to believe the man higher up had no connections with police, a member of the upper class rolling in cash by enslaving some of the most vulnerable members of the lower classes - in a way that's despised by general society - is nontheless an unusually provocative plot line for early American film.
