'Early in my research, a friend with excellent knowledge of the United Auto Workers internal operations told me, "Don't give up. They are hiding something"…'

It's 1990, and US labor is being outsourced to Mexico. Rumors of a violent confrontation at the Mexican Ford Assembly plant on January 8 reach the United Auto Workers (UAW) union in the US: nine employees had been shot by a group of drunken thugs and gangsters, in an act of political repression which changed the course of Mexican and US workers' rights forever.

Rob McKenzie was working at the Ford Twin Cities Assembly plant in Minnesota when he heard of the attack. He didn't believe the official story, and began a years-long investigation to uncover the truth. His findings took him further than he expected - all the way to the doors of the CIA.

Virtually unknown outside of Mexico, the full story of 'El Golpe', or 'The Coup', is a dark tale of political intrigue that still resonates today.
