During 9 years in the British Army, Shaun Pinner deployed on operations around the world. When he fell in love with and married a Ukrainian woman, the couple made their home in Mariupol. Missing the camaraderie and purpose he'd relished in the Royal Anglian Regiment he joined his adopted country's military as a sniper instructor. 4 years later, the section he led was on the frontline when Vladimir Putin's forces launched their invasion. Pinner's troops staged a fighting retreat back to Mariupol to join the remarkable, defiant last stand that captured the world's imagination. He fought on. Until, he was captured. Over the months the followed, the former British soldier required every ounce of strength, resolve, ingenuity and dark humour to see him and his fellow prisoners of war through the savage mental and physical toll meted out by his ruthless captors. But he refused to be broken.
