The story starts with Jak waking up in a cave, out of metals. He then escapes the cave by jumping into the river in the canyon below after licking a tin deposit on the wall of the cave. He is promptly recaptured by the Koloss who want to make him their leader and a Koloss. He discovers that his girlfriend Elizandra Dramali is Koloss blooded. He does not want to become a Koloss, so he says that he already is one and will prove it by getting the Survivor’s treasure from the bottom of a spear-shaped pool. He dives down, finds a chest, and brings it back up. It contains a number of Koloss spikes. The Koloss are so excited to have new spikes to increase their numbers, Jak and Elizandra manage to escape, and Jak realizes that the chest itself is made of aluminum.
