Teenage Devil Dolls aka One Way Ticket to Hell (1955)

Turns out it was made as a film student's masters thesis for $4,000,  about $42,000 today. In spite of the title, it was kind of a serious docudrama, silent with a Jack Webb-like voice over, about a teenage girl who spirals into drug addiction. They blame her mother's multiple divorces and her Mexican boyfriend. 

If it had been more home movie-like, I think I would have enjoyed seeing Los Angeles 70 years ago.

They say it was 61 minutes, but the one I saw was three minutes shorter.
