Free Party: A Folk History is an independently made, feature documentary following the birth of the free party movement in the late 80s and early 90s and the impact it's had on our present times. The film follows the inception of the movement, a meeting between ravers and the new age travellers during Thatcher's last days in power, and the explosive years that followed, leading up the infamous Castlemorton free festival in 1992 - the largest ever illegal rave, which provoked the drastic change of the laws of trespass with the notorious introduction of the Criminal Justice Act in 1994.
