A decade on from the withdrawal of British combat troops from Afghanistan, this film tells the story of a single group of soldiers from the Welsh Guards deployed to the frontline of the war in Helmand Province in 2009, built on the unfiltered accounts of ten men alongside testimony from their family members. Their bond was unbreakable, but across the six-month tour, their regiment took unprecedented casualties, losing a man at nearly every military rank up to lieutenant colonel, while many others suffered life-changing injuries.
