Modern British war film set during the Afghanistan conflict. When a sniper patrol stumbles upon a dried out river bed filled with land mines en route to a mission, it is up to a platoon from the parachute regiment to tend to the wounded and to orchestrate the group's escape. With every step there is the possibility of losing limbs and lives as the mines explode and shrapnel flies. This is the remarkable true story of how the soldiers planned an evacuation from the ridge in Kajaki, Helmand, and ensured a helicopter was able to land and lift them to safety without blowing their position and the troops apart.
