Somewhere in the depths of space, NASA astronaults return to Earth after collecting some mysterious golden rings they found inside a meteorite. One of the rings falls off the ship and triggers a hyperspace portal which summons Sonic the Hedgehog, an extraterrestrial blue hedgehog with the ability to run in nearly endless speeds. Sonic speeds around the planet vowing to retrieve the other rings which fell on Earth.
Elsewhere, Mandy Brooks is sent to Green Hill Adventure Camp to reunite with her twin sister Wendy, whom she has not seen in two years since their parents' divorce. Mandy lives with their father and Wendy lives with their mother. She is excited to spend the summer with Mandy. Reginald Everton is a funny African American and the son of a millionaire whose company has gone bankrupt.
Upset with her father claiming that she still has to wait for the right day to meet her sister, Mandy decides to spend a moment alone, on which she ends up encountering the golden ring which fell from the NASA ship, unexpectedly calling for Sonic, who soon befriends her. They both form a bond with each other until Wendy shows up and happily reunite with Mandy.
