Tails, Chris, Amy and Frances are in the X Tornado searching for the third Chaos Emerald. Chris is wearing goggles that were a gift from his teacher, Mr Stewart. Unbeknownst to him, Mr. Stewart is actually a government spy and the goggles contain a tracking device and microphone. Stewart is following in his car.
At the White House, Rouge, Topaz and the Captain are meeting with the President and two government officials. The President praises them for finding Dr. Eggman's engine room on their first mission. They plan a full-scale assault against Eggman's base, which will cover a small covert incursion to destroy the base from within.
An envoy led by the Secretary General Jerome Wise shows up at the mansion, hoping to meet Sonic. Ella refuses to let them in and denies knowing who Sonic is. She throws a bucket of water over Wise before sending them away.
Tails locates an Emerald in a corn field, and lands the X Tornado. He presses a switch and the plane transforms into a walking mech, the X Cyclone. The find the precise location where the Emerald is buried, and Chris and Francis run off to look for shovels or something to dig with.
As the navy moves in to attack, a fake news report is broadcast so that Eggman leaves to collect the Emerald in the corn field. He departs with the E-35, a large chicken-shaped robot with a fan in its chest.
They arrive at the field and E-35 activates its fan, which uproots the corn, sends Amy flying and knocks over the X Tornado. Chris' goggles are blown away, which leads Mr. Stewart away from the field.
The President announces on TV that a campaign against Dr. Eggman has begun. Cream sees the broadcast and rushes to tell Sonic. Sonic and Cream find that Tails is missing, so they won't be able to fly to Eggman's base.
Mr. Stewart finds Chris' goggles, but Chris is nowhere nearby. He decides to double back and soon finds the field where the E-35 is active. He calls the mansion and Sonic sets off to help them.
