February 1968. From South Vietnam the explosive Teêt Offensive has dealt a final blow to shattered US troops and sparked a worldwide appetite for insurrection. Left destitute by standards of living and provoked by a three-year war on their ideological comrades, student leaders across Europe rise up with a single voice ‘We shall fight. We will win. Paris, London, Rome, Berlin.’ Within six weeks, 20,000 protesters will besiege the American embassy in London’s Grosvenor Square. It is the Spring of Discontent, and revolution is the air.
