A large number of Chao have disappeared, leading Sonic the Hedgehog and Miles "Tails" Prower to immediately adventure out to find them. It turns out that Eggman Nega (once again masquerading as Dr. Eggman) has kidnapped the Chao and hidden them inside a haunted mansion. Upon learning of an interdimensional beast known as the "Ifrit" from Gerald Robotnik's journals, he discovers that it becomes more powerful after consuming Chao and plans to unleash it to destroy the world. However, to open the portal to the Ifrit's world, all seven Chaos Emeralds are required, so Eggman Nega secretly hires Rouge the Bat to collect the Emeralds. The Master Emerald has also gone missing again, and Knuckles the Echidna teams up with Rouge to find it.

Amy and Cream are relaxing at a beach. when they saw a note saying that Eggman Nega had kidnapped Big and Froggy and took him to the Egg Carrier. So they head out to save him.

Meanwhile, Silver the Hedgehog has returned from a now ruined future caused by the Ifrit. In order to make a better future, he collects the remaining Chao and hides them. Vector orders Espio to observe Silver, believing Silver to be the culprit behind the missing Chao. After working with him for some time, Espio discerns Silver is trying to save the world and helps him on his mission.

The real Dr. Eggman sends Metal Sonic to find Shadow to tell him of Nega's plans. Shadow and Metal Sonic then set out to retrieve the Chaos Emeralds before he does, Eggman continuing communication through Metal Sonic.

All of the teams gather at the haunted mansion where the portal to the Ifrit's world is located. Despite Rouge only collecting six of the Emeralds, the portal opens. Nega dispatches his upgraded version of Metal Sonic, Metal Sonic 3.0, to awaken the Ifrit. Despite possessing the minds of Sonic, Tails, Knuckles, and Rouge (depending on who the player plays as), the Ifrit is defeated by the heroes. Shadow and Metal Sonic destroy the Ifrit and close the portal, but trap themselves, along with Eggman Nega, in the Ifrit's dimension. However, Metal Sonic tears his chassis open, revealing the 7th Chaos Emerald. Shadow uses the Emerald to teleport Metal Sonic and himself back to their dimension, leaving Nega behind.

Sonic and Tails rescue all of the Chao and bring them to a Chao Garden.

Knuckles finds the Master Emerald using the Emerald Detector that he and Rouge stole from Eggman Nega. Rouge steals the Master Emerald and runs away, with Knuckles giving chase.

Silver returns to what he hopes is a happy future while Espio has to answer to an angry Vector, who had spent their client's advanced payment on late rental fees.
