Sonic, Sonia, and Manic are looking for the Royalcy of Mobius in an abandoned old factory. They are ambushed by Dingo, Sleet, and a bunch of Swatbots. The three hedgehogs destroy a number of Swatbots and escape. They get in their van and Sonic drives them through a wasteland to the hilly Valley Resort. They are greeted by Stripes, who welcomes them and puts them up in a nice room. Stripes seems to be interested in Sonia. Sonic is suspicious of Stripes' loyalty.
Stripes is in contact with Robotnik. He tells him that he has two visitors instead of three. Robotnik says that if they are members of the resistance he must roboticize them.
The next day Sonic and Manic go exploring around the village. Stripes comes to their room and courts Sonia. Manic mentions being part of the resistance to a citizen and the whole town turns against him. Sonic saves Manic and they figure out this place is strange because the people side with Robotnik.
While on a date with Sonia, Stripes explains that the only way to survive is to make a deal with Robotnik. Sonia disagrees and makes Stripes stomp away angry. Sonia sings a pop song. Manic and Sonic find Sonia and they suspect that Stripes works for Robotnik.
Later that night, Sonic spies on Stripes as he calls Robotnik. Stripes says Sonic and Manic are there. Robotnik asks about Sonia. Stripes lies and says he has not seen her. Robotnik hangs up on Stripes and orders Sleet and Dingo to go destroy the valley, insisting he doesn't need Stripes' help anymore.
Sonic tells his siblings that Stripes ratted them out to Robotnik. Sonia gets angry and says she doesn't believe him. The Hedgehogs confront Stripes and he tells them the truth. He explains that he is only in cahoots with Robotnik to protect his valley and that the resistance is useless. He says he told Robotnik about Sonic and Manic, but not Sonia. Sonia says she would never abandon her brothers or the resistance.
Sleet and Dingo show up with Swatbots and prepare to roboticize everyone in the valley. Machines start destroying all the trees. The Hedgehogs get away, but Sonia doesn't want to run away, she wants to help Stripes. The Hedgehogs return and rescue Stripes from the roboticizer. All the citizens come out of their homes and attack the Swatbots. Sonic destroys the robots and they throw Sleet and Dingo out.
The next day, the hedgehogs are leaving. Stripes and his people tell them they have joined the resistance and invites Sonia to fight by his side. Sonia insists on staying with her brothers and they depart hoping to meet Stripes again some day.
