Poorly directed with a weak script and lacking character development, it tells the story of 6 idealistic peasants called the Lions of San Pablo who join Pancho Villa's army. The film is cut up into episodic segments each ending in the noble death of a soldier. Themes of disillusionment and disenchantment permeate the film.
War is never glamorous, often not fought honorably either: Often the most heroic die while the cowards and opportunists survive and prosper. This film depicts war in precisely that fashion.
Finance Banks subsidized the making of this film and upper-class critics lauded this terrible film, not due to its artistic merits (which it lacks), but due to it's anti-revolutionary message. It depicts Villa as a monster and the revolution as evil. It is pure propaganda failing to show the suffering and starvation of the majority of the population, who were peons (debt slaves). It was their desire to end this suffering and create a better world that led to the Mexican Revolution. Pancho Villa wasn't a saint. He was a man. However, the peons and workers wouldn't have joined or supported Villa's army if he had been a monster. True the revolution came to an end, but not because Villa or Zapata were inhuman men, but because the suffering peons could not compete with American-made machine guns imported by the Obregon regime who supported big American corporations in Mexico. In fact, Villa & Zapata were so popular, they had to be assassinated: Zapata in 1919 & Villa in 1923.
The revolution though was from a failure, however, as unions became legal, working conditions improved, and land was redistributed to the peasants. This film is straight revisionism (rewriting of history). In fact, its original ending had to be changed. It was so anti-revolutionary there were fears of rioting by many Villa's followers.
