Zagor and Tonka, long time friends, blood brothers and allies in a thousand battles... Their friendship, though, seems bound to sour, when the stunned Mohawk chief realizes that the Spirit-with-the-Hatchet is helping a group of businessman to move White settlers to the Plain of the Little Water, a placed held as sacred by all the tribes in Darkwood. Determined to ask his friend for an explanation, Tonka is staggered after seeing Zagor kill a young warrior in cold blood, and throw his body in the river. At that point, Tonka wrath unleashes his wrath... What happened? Why is Zagor behaving this way?
