One Day in November (1976)

It is the story of a young man named Esteban, who was totally devoted to the cause of the Revolution against Fulgencio Batista. One day, Esteban is diagnosed with a cerebral aneurism, which causes him to take stock of his life as a revolutionary and to reconsider his relationships to his family--to his mother and brother, particularly--and his friends.
