When a co-worker gets contaminated she is irritated by how poorly treated they are with the incident being played down.
Later after her own contamination scare she gets involved with the local union branch and begins to note down all the lax safety practices.
No good will come of this.
This biopic of a 70s whistleblower refers to things before my time but things don't really change.
Movies do though and this is very much a product of its time. A modern telling would feel the need to create more drama with some shadowy cabal on screen. Here all we see is Karen's slow turn to quite low level activism and scenes from her life leading up to her suspicious death.
There is hostility from plant management and colleagues fearful for their jobs but all at an entirely naturalistic level. Like they went and filmed reality with very little extra spice for the camera. Right at the end there's an allusion to foul play in the circumstances of her death but it feels heavy handed given the tone of the rest of it.
Interesting but shows its age 6/10.
