Set in the early 1930s in a fictional capitalist country, the film follows three young women—Louise, Ellie, and Anni—who are thrown out of work by a devastating economic crisis. Their dreams of a better life collapse: Louise hopes to marry her fiancé, Dick, a young worker and
Komsomol member, but finds herself humiliated at the labor exchange and ultimately takes a job at a weapons factory. Spoiled and shallow, Ellie spirals into despair and resorts to prostitution in her pursuit of an easy life—her degrading encounter with the repulsive Prince Sumbatov becomes a stark symbol of her downfall. Only Anni, a committed communist, endures hardship with dignity, dedicating herself to the revolutionary cause as part of the "
Red Front". Meanwhile, unrest brews at the local arms factory, where workers are being recruited to fulfill a large order for weapons destined for imperialist wars in China and South America. Dick, alongside his comrade Kurt and other communists, urges the workers to reject participating in what they call the "conveyor of death". But hunger and desperation push many to accept the work—Louise among the first. A clandestine resistance begins. Dick is arrested while distributing anti-war leaflets, but he escapes. The workers rise up against the police and emerge victorious. A strike breaks out at the factory, and for the first time, even those who once stood aside from the class struggle—like Louise—join the fight. == Background ==
