We buy too many clothes, and we pay too little for them.

That's the message of "The True Cost," a new documentary on the perils of the fashion industry, which is being released next week.

The film is a sweeping, heartbreaking and damning survey of the clothing economy. It covers malformed children of pesticide sprayers in India's cotton belt, gruesome shots of the deadly 2013Rana Plaza factory collapse in Bangladesh, Indian rivers frothing with chemicals, and mountains of discarded clothing in Haiti.

"I believe these clothes are produced by our blood," Shima Akhter, a Bangladeshi factory worker, says in the film. "I want the [factory owners] to be aware and look out for us, so that no more mothers lose their kids like that."
