A 1970 film directed by Martin Ritt, starring SeanConnery, Richard Harris, and Samantha Eggar. The movie tells the story of a 19th-century group of Irish-American coal miners who form a terrorist group known as the Molly Maguires to fight exploitation by their oppressive employers. A PinkertonDetective named James [=McParlan=] infiltrates the group to take them down from the inside. But he finds himself sympathizing more with the Mollies than with the company men who hired him.
The film takes a few small liberties with the plot, sacrificing strict historical accuracy for drama, but the setting is highly realistic and occasionally beautiful. It was a box office flop, but well worth watching.
