Sonic and his siblings travel to the outskirts of Mobius to recruit a tribe of nomads for the Resistance. The Hedgehogs van breaks down and they are saved by the tribesman. Once they return to the camp, Manic discovers that the chief has been roboticized, which is a secret that could have the chief banished from the tribe. Manic is then captured and taken from the camp, unbeknownst to Sonic, Sonia and the chief. Sonia and Sonic get to the bottom of why their brother is missing and rush to find him before it is too late.
