Paratrooper commander Colonel Mathieu, a former French Resistance fighter during World War II, is sent to Algeria to reinforce efforts to squelch the uprisings of the Algerian War. There he faces Ali la Pointe, a former petty criminal who, as the leader of the Algerian Front de Liberation Nationale, directs terror strategies against the colonial French government occupation. As each side resorts to ever-increasing brutality, no violent act is too unthinkable.
