Three stories reconstructing the start of the triumphant Cuban revolution which deposed Batista.

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.

Frustrated with their lack of upward mobility, some young Italians move to Cuba to start a wi-fi café and attempt to build a new life.

A squad of young Cuban armed forces recruits are tasked with defending a strategic key north of Cuba. The fraught relationships between the young soldiers and the sergeant who leads them transform as they discover his human qualities during training and learn discipline in the harsh conditions of their post.
