Based on real events and real people, this is the story of Davy, a young national serviceman from the Forest of Dean. Having volunteered for active service, he finds himself on a hilltop, south of the River Imjin in Korea, waiting with the Gloucestershire Regiment for the Chinese People's Volunteer Army to attack. What follows earns the regiment a US citation for bravery and changes the young soldiers' lives forever.
Taken into captivity, Davy and his fellow 'Glosters' endure malnutrition, hunger, disease and beatings in the brutal POW camps in North Korea. Friendship, bloody-minded determination and learning how to beat the system become their only means of survival.
