A Terrible Beauty

Dermot O'Neill is recruited into the Irish Republican Army (IRA) during the Second World War. His girlfriend breaks up with him, telling him the IRA will turn him into a murderer. He and his friend are chosen from their unit to participate in a raid on a British armoury to steal weapons and ammunition. The theft goes off without a hitch, but their next attack, to destroy a guarded power plant in concert with a planned German invasion, results in bloodshed.
