The Castro revolution was just consolidating its power when, in 1961, over 100,000 students were sent from their schools into the countryside to teach the peasants there how to read. Coinciding with the Bay of Pigs invasion, in this docudrama, 15-year-old Mario (Salvador Wood) has come to a tiny village in the Zapata swamps and gradually wins the villagers over to his task. At the same time, he receives an education in the realities of rural life from the hard-working peasants.
