In the movie, a young woman named Natsumi (Ai Takeuchi) is forced
into factory slave labor to repay a debt. The security chief, Tsukada,
assigns her to a group of female workers led by Atsuko (Nagisa Umeno).
The factory is a hellish place, and whenever a breach of discipline
occurs, female workers are routinely raped by their overseers. Natsumi
is at risk of being the next victim, but she has a plan to bring the
entire operation down first.
Captive Factory Girls was followed by Captive Factory Girls 2: The Revolt in 2008.
