Reacção em Cadeia

Karen Silkwood (Streep) lives a free-spirited existence with two friends (Kurt Russell and Cher) who work with her at an Oklahoma nuclear facility. It's only when she discovers she's been exposed to radiation that Karen's conscience awakens, and soon she is digging for evidence of wrongdoing at her company. But her sudden zeal for safer working conditions may come at a high price as she alienates friends and possibly even puts her own life in peril. (texto oficial do distribuidor)
