This gritty Italian film looks at the world of organised football violence. A group of AS Roma supporters known as 'Poison Brigade' are led by the brutal Pincipe to battle it out with rival Juventus supporters, following a match in Turin. Loyalties are tested within the group when Principe's best friend Red assumes control of the group, causing bad blood within the 'Poison Brigade'... but that's nothing compared to the blood shed when the two football firms eventually clash.
