The "killer bargain" referred to by this hard-hitting documentary's title is the availability of cheap consumer goods, imported by Western companies, whose prices don't reflect the actual human and environmental costs associated with their production in the developing world. Consumers remain largely unaware of the conditions under which the goods they buy are produced; this film makes those connections shockingly clear. While some retailers and manufacturers refuse to talk to the filmmakers, workers, doctors and scientists testify eloquently to the tremendous human costs of globalization.
