Twice every year the Italian city of Siena hosts the Palio, the oldest horse race in the world dating back to 1400. It is a horse race unlike any other. It's a bare back horse race consisting of several laps around the town's central piazza. Even a horse that has lost its jockey can still win the race! And losing jockeys can be viciously attacked by the crowds. The city is divided into 17 districts, and each district competes for prestige and pride. For the residents of Siena the Palio is a metaphor for the vagaries of life and represents a microcosm of life and traditions of Italy itself. But the outcome of the race is more often than not determined by strategy, bribery and corruption, and side deals between the various jockeys and racing teams. In this fascinating documentary, director Cosimo Spender (Without Gorky, etc) takes us behind the scenes for this revealing and disturbing look at the tradition of corruption that has dominated the sport. He briefly gives us an overview of the history of the sport, and we meet some of the legendary past figures from the sport. In the lead up to the 2013 event Spender has been granted an unprecedented level of access to some of the competitors. He follows several of the competitors, including the arrogant veteran jockey Gigi Bruschelli, who has won 13 Palios, and his younger protégé and main rival Giovanni Atzeni. Atzeni is in it purely for the sport and the thrill of racing, unlike the venal champion who has ruthlessly dominated the sport. Spender and his team of cinematographers and editor (Valerio Bonelli) have captured the frenetic adrenaline-charged and pulse pounding excitement and brutal spectacle of the race itself, but it is the behind the scenes machinations that provide most of the intrigue and drama. Lovers of horses though should be warned that some scenes here could prove distressing.
