Boxcar Bertha

The head of the railroad shamelessly exploits the workers in the 1930s.
But union organizer Bill Shelley, along with the Brotherhood of Workers, fights back. When legal options are exhausted, Bill forms a gang of noble robbers. When a comrade accuses him of using inappropriate methods, he responds, "I'm not a criminal; I'm a union member."
The plot features scenes of eroticism and violence (it was the 'wild' 70s, after all). Bill is played by the legendary David Carradine (Kill Bill).
