End of the Spear is a 2005 American drama film that recounts the story of Operation Auca, in which five American Christian missionaries attempted to evangelize the Huaorani (Waodani) people of the tropical rain forest of Eastern Ecuador.

Based on actual events from 1956 in which five male missionaries were speared by a group of the Waodani tribe, the movie tells the story from the perspective of Steve Saint (the son of Nate Saint, one of the missionaries killed in the encounter), and Mincayani, one of the tribesmen who took part in the attack.

The two eventually formed a lifelong bond that continued until Mincaye's death in April 2020.
