This winter, the fifth estate cameras were granted four weeks of unprecedented and exclusive access to the NATO trauma hospital at the main military base in Kandahar Province. It's one of busiest trauma hospitals in Afghanistan and it has been under Canadian command for two years. Many of the medical staff are career soldiers in Afghanistan on a six-month tour. Civilian doctors and nurses can also work at the hospital, usually for a six-week tour. For them, it's a crash course in treating injuries they might never see at home. Their reasons for going there are complex and individual. Wherever you stand on Canada's Afghan mission, you will want to meet these remarkable professionals as they work under the constant pressure and complexities of modern warfare.
