Plot summary
Ireland, 1920. Damien and Teddy are brothers. But while the latter is already the leader of a guerrilla squad fighting for the independence of his motherland, Damien, a medical graduate of University College, would rather further his training at the London hospital where he has found a place. However, shortly before his departure, he happens to witness atrocities committed by the ferocious Black and Tans and finally decides to join the resistance group led by Teddy. The two brothers fight side by side until a truce is signed. But peace is short-lived and when one faction of the freedom-fighters accepts a treaty with the British that is regarded as unfair by the other faction, a civil war ensues, pitting Irishmen against Irishmen, brothers against brothers, Teddy against Damien.... Written by Guy Bellinger

The commercial interest expressed in the United Kingdom was initially much lower than in other European countries and only 30 prints of the film were planned for distribution in the UK, compared with 300 in France. However, after the Palme d'Or award the film appeared on 105 screens in the UK, more than three times larger than the UK release for any of Ken Loach's previous films.
