Fred is a deliciously evil character by the way, he basically whores out his sister Claire (Sheila Terry) to try and keep Cole out of the way...
Cole, assisted by his secretary Mary (Maxine Doyle) and her brother Joe (Rex Lease) the superintendent work to try and save the mine from low production, accidents and worker unrest led by Johnson's agent Dorsky (Matthew Betz). The film isn't very exciting until the final plot below ground but is interesting enough as a drama especially with respect to labour relations and health and safety pre-war.
