Four storylines are followed. The first is set in the modern world, where The Dear One (Mae Marsh) and her beloved The Boy (Bobby Harron) are struggling to survive. He loses his job due to union striking after a pay cut mandated so that the company boss can fund his sister's charity work. That same charity takes away the Dear One's child, citing neglect, as the Boy is sent to jail after resorting to crime.
The Biblical "Judean" story recounts how intolerance led to the crucifixion of Jesus. This sequence is the shortest of the four.
The third story details the events of the St. Bartholomew's Day Massacre of 1572 where Huguenot protestants were killed under orders of the Catholic royalty.
The fourth story is set in ancient Babylon, and deals with a religious struggle between different sects that leads to their conquest by the Persians.
Griffith's masterpiece is a marvel of narrative and structural complexity for the time, and the Babylon scenes are truly awe-inspiring in their scope and ambition. The story, in which instances of "intolerance" are illustrated throughout the ages, is a bit muddled and more than a little pretentious, but the visualization is second-to-none.
It's been put forth that Griffith made this as a sort of apologia for the racial insensitivity of his previous mega-hit The Birth of a Nation, but Griffith scholars disagree, and say that Griffith was never ashamed by the racist nature of his last movie, and that the intolerance that he was speaking out against was that which had been directed at him over that film (shades of our current political climate).
Regardless, this ended up being the most expensive film ever made up to that point, and was a major flop at the box office, from which Griffith never really recovered. The film now stands as a colossal achievement, and a precursor to historical epics to come. There are various versions in circulation.
