Andrew Lang directs this documentary following an eight-month period in the lives of three pupils at the Havana Boxing Academy. The three 10-year-old boys are training for the most important event of their lives: Cuba's National Boxing Championship for Under-12s. But crisis strikes as the season gets underway when the country's iconic long-time leader, Fidel Castro, is suddenly taken ill. With all of Cuba's Olympic boxing champions defecting to the USA, the boys must quickly adapt to a changing world.
