Age of Heroes
In 1940, Major Jones is assigned to assemble an 8-men commando team to travel to Norway with specialist Roger Rollright to meet the agent Beowulf and destroy the German Freyo Station and steal German state-of-the-art technology of Radio Direction Finding (RDF) in Operation Grendel.
Jones travels to the Dashwood Military Prison to bring the soldier Brightling and he brings also the insubordinate Corporal Bob Rains; then the commando team heads to Scotland to be trained.
When they fly to Norway, they are discovered and the plane crashes. Six members of the military unit and the specialist survive to the attack. After the assignment, the naval pickup is not possible and the survivors without supply and little ammunition need to walk to Sweden in a dangerous journey through a land occupied by German forces.
