It is midsummer 1973 in Hyde Park and the flower power movement is at its height. Hippies, hipsters, rock stars, musicians, wild women and global nomads with Shamanic horses gather to play, sing, dance, protest and perform. Policemen and a family of out-of-towners get caught up in the celebrations. Will they get in the groove? Nell Gifford builds a pleasure dome and Tweedy has a job in the kitchen as he thought everyone was talking about “Flour Power”. As evening approaches, the ever more chaotic event careers towards a joyful, transcendental finale. Be there or be square!
