Movie about the Matewan Massacre. Coal mining union against a coal mining company set in 1920.

Movie is from 1987 but being set in 1920 has aged very well. Great cast including the President of the 12 colonies from the Battlestar Gallactica reboot (Mary McDonnell) among many other great actors.

Highly recommended. Currently streaming on Prime where I live.

edit: Contains an eyewitness account by the narrator.
