Newly qualified barrister Roger Thurnsby finds his first few appearances in court land him in all kinds of trouble...

This film is based on the true story of Pastor Martin Neimuller, who was sent to Dachau concentration camp for criticising the Nazi party. The small German village of Altdorf in the 1930's has to come to terms with Chancellor Hitler and the arrival of a platoon of Stormtroopers (preceded by a flock of sheep - subtle). The Stormtrooper go about teaching and enforcing 'The New Order' but Pastor Hall is a kind and gentle man who won't be cowed. Some villagers join the Nazi party avidly, some just go along with things, hoping for a quiet life but Pastor Hall takes his convictions to the pulpit.
