The behind-the-scenes story of how Margaret Thatcher defeated the miners in 1984/85 and changed the face of Britain forever, featuring contributions from Downing Street insiders and those involved in the bloody pitched battles between those on strike and those who wanted to work. The documentary also examines the critical role of her secret weapon, David Hart, an Eton-educated avant-garde filmmaker, an "irregular" who worked with Thatcher behind the scenes. He was her enforcer and ultimately delivered the final blow.
