Is it a true story? SPOILER
I watched it thru Netflix last week and noticed at the end it had a write up that the town of Sutcliff had lost 9000 (?) lives thru what they think was
spraying of a poisenous substance cyanide (?) and it seemed to be a big coverup. My guess is that milk got contaminated and somebody didn't want it known. The Government had no comment on it. So is this a true story or and if so I'm wondering how much of it if any was made up for the movie.
