Diego Mora is a long-serving member of the Spanish communist party, now acting as a clandestine go-between for activists living in exile in France and covert militants operating in Spain. At a border control on his return to France, he is nearly arrested, but he saved by his forged documents. Arriving in Paris, he meets Nadine, the daughter of a sympathiser, and then rejoins his former lover Marianne, who wants to settle down with him. Diego is frustrated in the way events are turning out in his country and voices opposition to plans for a national strike and terrorist activity. Inwardly, he seems to feel the war has been lost. Then he realises that he has caused the arrest of his colleagues in Spain and must return to his country to prevent further arrest.
