The Lighting of the Beacons, from the Lord of The Rings, the Return of the King

Having Accepted Defeat in the Face of Overwhelming Odds, the Steward of Gondor Won't Call for Aid.

But Gandalf the Wizard, who Still Has Hope for the Victory, enlists the Aid of the Hobbit Peregrin 'Pippin' Took to Light the First Beacon Fire, and thus ... "Hope is Kindled".... as the beacon keepers on a vast chain of mountain peaks transmit the call for help to Rohan, setting the stage, after a long battle, for the Return of the King.

One of the most important sequences in the entire Trilogy.
