Giant - Murder Underground

How did Canada’s deadliest labour dispute begin? By the 1990s the once-booming ‘Giant’ Gold Mine in Yellowknife is nearing the end of its lifespan. It’s bought by an ambitious American woman named Peggy Witte who is determined to make a profit with what remains — but the union’s convinced she’s out to bust them.

The hostility between the union and the company boils over when union members vote to go on strike, but are locked out by the company first. Peggy Witte brings in replacement workers, infuriating strikers who resort to escalating levels of violence, that spills into the city.

On September 18th, 1992, nine men showed up for work at Giant Mine, but never made it out. Grief and anger spread throughout the city as investigators try to piece together how a fatal explosion happened underground.

Police begin what still stands as one of the most labour intensive murder investigations in RCMP history. Investigators hone in on two suspects. Union members believe the police are on the side of the company and unfairly targeting them.

The RCMP make a huge breakthrough when outside polygraph expert Greg McMartin suspects an overlooked miner set the blast. McMartin flies to Yellowknife to interview the man face-to-face, convinced he’ll be sharing the room with a murderer.
