February 1939. Overwhelmed by the flood of Republicans fleeing Franco's dictatorship, the French government's solution consists in confining the Spanish refugees in concentration camps where they have no other choice than to build their own shelters, feed off the horses which have carried them out of their country, and die by the hundred for lack of hygiene and water... In one of these camps, two men, separated by barbwire, will become friends. One is a guard, and the other is Josep Bartoli, a cartoonist who fights against the Franco regime.
