You don’t have to be killed in action to be a casualty of war.
Medics Paul Adams and Lizzie Jarman are one of the most welcome sights to injured soldiers in the war-torn poppy fields of Afghanistan.
With red crosses on their arms and medical equipment strapped to their backs, they thunder into battle in a Chinook helicopter – straight into areas everyone else is desperate to get away from.
In the middle of the fiercest fighting British troops have seen since the Falklands War, the medics are the last defence from death on the ground in some corner of a foreign field. But in Afghanistan, where a hostile is only obvious when they raise a weapon, there’s no such thing as a non-combatant. And not all enemies are on the other side.
Despite the heroic efforts of the medics on the ground and in the air, someone in the field hospital is determined to finish what the Taliban has started. Wounded soldiers – who should be living – are dying. Their deadliest enemy is much closer to home than they realise.
As the death toll and the temperature rise, can the medics finish their tour of duty, or will it finish them?
