Sonic is an extraterrestrial blue hedgehog who can run at supersonic speeds. His caretaker, Longclaw the Owl, encourages him to hide his powers, but Sonic does not listen, resulting in a tribe of echidnas attempting to abduct him. Longclaw gives Sonic a bag of rings which open portals to other planets, using one to send him to Earth while she holds off the echidnas. Sonic spends the next ten years living in secret in the town of Green Hills, Montana. He idolizes the local sheriff, Tom Wachowski, and his veterinarian wife, Maddie. Tom has recently been hired by the San Francisco Police Department and is preparing to move.
Although he enjoys his life, Sonic longs for real friends. One night, he plays baseball by himself and, after realizing his loneliness, becomes upset and starts running around the field. The energy Sonic emits creates an electromagnetic pulse that knocks out power across the Pacific Northwest. The United States Department of Defense enlists roboticist and scientific genius Dr. Robotnik to help discover the cause of the outage. Robotnik discovers and tracks Sonic, who hides in the Wachowskis' shed. Just as he is opening a portal to escape through, Sonic is discovered and shot with a tranquilizer by Tom, causing him to drop his bag of rings through the portal, which leads to San Francisco. After Sonic awakens, Tom reluctantly agrees to help Sonic recover the rings. Robotnik invades the house, but Sonic and Tom escape. Robotnik comes across one of Sonic's quills and has Tom declared a domestic terrorist.
Tom and Sonic narrowly evade Robotnik and grow closer as they journey to San Francisco. Tom learns of Sonic's desire to make at least one real friend. Meanwhile, Robotnik slowly loses his sanity as his search for Sonic becomes more obsessive. Sonic disapproves of Tom's decision to leave Green Hills, arguing that he is leaving his true friends. Sonic is injured by one of Robotnik's drones shortly before the two arrive in San Francisco, where Tom is reunited with Maddie. Maddie helps revive Sonic, and the three travel to the Transamerica Pyramid, where Sonic's bag of rings landed. Robotnik and his robots attack them at the top, but Sonic uses the rings to teleport Tom and Maddie back to Green Hills before taking on Robotnik. Using the power of Sonic's quill, Robotnik achieves supersonic speed and pursues Sonic across the world.
Robotnik and Sonic's fight eventually makes it back to Green Hills, where Robotnik overpowers Sonic. However, Tom intervenes, and Sonic regains his strength after Tom refers to him as a friend. Sonic reclaims the energy that Robotnik is using. With help from Tom, Sonic uses a ring to send Robotnik to a planet made of mushrooms. With Robotnik defeated, Tom and Maddie decide to stay in Green Hills and let Sonic live in their house with them. The US government erases all evidence of the incident, including records of Robotnik's existence. However, Robotnik, still in possession of Sonic's quill, begins plotting his revenge.
In a mid-credits scene, Tails, an anthropomorphic two-tailed fox from Sonic's world, emerges from a ring portal in search of Sonic.
