The final part shows Mariano, a typical farmer, who rejects the requests of a revolutionary soldier to join the ongoing war. The soldier appeals to Mariano's desire for a better life for his children, but Mariano only wants to live in peace and insists the soldier leave. Immediately thereafter though, the government's planes begin bombing the area indiscriminately. Mariano's home is destroyed and his son is killed. He then joins the rebels in the Sierra Maestra Mountains, ultimately leading to a triumphal march into Havana to proclaim the revolution.
