Representatives of the mysterious Bird tribe arrive at the Privileged complex to meet with Harmony and uneasiness arises when their leader claims that the birds always "take whatever they want." Dan and Erin plan to journey to the forbidden zone to see if they can obtain more information and interpret the true meaning of Faygar's prophecies.

Now in control of the Privileged tribe, the Harmony panics when she discovers she has a spot. That is not the perfection she demands in everyone, let alone herself. Sky and Dan arrive back at the Ant camp with the Stranger as a prisoner and return all of the items he stole. Faygar is concerned about the prophecies and prays for guidance, as the Stranger begins to make ominous patterns with grain.

After realizing that they have both been so suspicious of each other, Harmony and Shadow consider teaming up, believing that they both have a lot in common. At the Barb camp Dan wonders whether Gwyn truly wants to be a Barb or not. Sky worries if he is a descendant of the ancient ancestor, Zoot - the source of much frightening folklore.

The Ants and Barbs celebrate their victory against the Privileged and ponder what to do about Flame who is now held prisoner. Shadow is brought into the Discard camp by Warp guards and Sky discusses escaping. 'Things' begin to go missing in the Ant camp, including Erin's bike, and the Stranger continues to furtively observe all the inhabitants.

During his strict training process, Flame searches for a suitable sparring partner as preparations continue for the attack on the Ant tribe. Gwyn tries to settle into her life as a Privileged but can't help missing her brother. The Ants learn that the Warps have tricked them. Cass and Omar try to convince a reluctant Faygar to meet with Zora. Dan attempts to join the Barbs.

After running away from the Ant tribe, Dan finds himself alone in the forest. Zora tries to contain her second-in-command, who doesn't trust Sky. At the Ant camp, Omar is happy that Sky and Dan have both left. In the Privileged tribe, Shadow prepares the Warps, for an attack on the Ant camp. Shadow advises that they will be ready in a week but Flame wants the attack to happen the next day.

Sky, Faygar and Gwyn continue their work with the Discards while remaining prisoners at the Privileged stronghold. In the Ant camp tensions rise as Cass and Omar are unhappy about sharing the camp with the Barbs. Erin falls in love with Kwarli's bike and causes havoc as he struggles to learn how to use it.

Zora moves the Barbs to the Ants' camp. Some Ants aren't too happy to have new neighbors. Flame instructs the invincible Shadow to fight Sky in hand to hand combat, so everyone can witness Sky's real weaknesses. Kwarli discovers an old contraption in the Ant camp which he believes was once called a bicycle, and Erin is intrigued by the notion that it could be a descendent of an ancient machine.

Flame is uneasy that the Stranger's presence might mean they're all doomed. Zora tries to calm down Faygar but all are not entirely convinced that the Stranger poses no threat. Omar and Kwarli look for a way to escape their Privileged cell. Leanne and Erin find a small machine, which comes to life and seems to pursue them into the Ant camp.

The mysterious Stranger lashes out when Erin touches one of the stones the Stranger is using to build a small tower, which bears a significant resemblance to the group of rocks in the forbidden zone. The Ants and Barbs agree that they can't trust Sunni or Harmony, and decide on an unexpected resolution with the Bird tribe as the very future of all concerned is under real threat.
