Merlina, Merlin's granddaughter, on the run from a pursuer, summons Sonic to help free the mystical realm from King Arthur, who has been possessed by an unknown evil stemming from the sheath of Excalibur, and is now ruling the kingdom as the tyrannical Black Knight. Sonic's speed alone will not end the Black Knight's reign, so he must take up the talking sword, Caliburn, and master swordsmanship to break Arthur's curse and save the kingdom.

In the World of Camelot, while fleeing from the Black Knight and his demonic minions from the Underworld, Merlina is surrounded by the Black Knight's minions, and before being taken, she performs a summoning ritual that brings Sonic to her world. Sonic defeats the Black Knight's minions before Merlina teleports them both away in a whirlwind. The Black Knight sends his three Knights of the Round Table, who are still loyal to the Black Knight despite their evil, to find and kill Sonic and Merlina on sight. Merlina explains that the Black Knight, once King Arthur, is immortal, as he possesses the sheath of Excalibur. After training Sonic in the art of the sword, Merlina explains that King Arthur was once a wise and just ruler, but became corrupted by the power of immortality granted by possession of the sheath of Excalibur. Sonic acquires Caliburn, a talking sword who is very skeptical of Sonic's abilities, and they set out to find him while Merlina hides (Merlina explains that she would be recognized in town). They first find the Blacksmith (Tails' counterpart in the game) in Castle Town, to sharpen Caliburn's sword. The Blacksmith recognizes Caliburn, but can't remember when he's ever heard of her name.

Sonic heads off to see Nimue, the Lady of the Lake (Amy's counterpart in the game) and the previous owner of Excalibur's sheath, to find out how to stop the Black Knight; along the way, he encounters and defeats Lancelot (Shadow's counterpart in the game), one of the Knights of the Round Table, and claims his sword. The Lady reveals that she will only help Sonic when he becomes a true knight and she presents him with three trials to complete in three days. After completing them, Sonic soon encounters a crying boy, whose village was kidnapped by a dragon, and decides to help him. Sonic soon finds and defeats Gawain (Knuckles' counterpart in the game), and takes his sword before he can kill himself out of shame, asking him if there is more to being a knight than serving a king. With the townspeople saved, Nimue reveals that she was the crying child testing Sonic, and that she can dull the sheath's power by retrieving the Holy Swords wielded by the Knights of the Round Table. Sonic then encounters Percival (Blaze's counterpart in the game) and defeats her before stopping her from falling off a cliff, an act that ultimately earns him Caliburn's respect and the title of "Knight of the Wind". Merlina has watched those events from her reflection pool, and arrives to inform Sonic that the Black Knight is in Faraway Avalon. Sonic and Caliburn pursue and defeat the Black Knight with the power of the three Holy Swords.

After fighting and defeating him with all four Holy Swords (including Caliburn), Merlina reveals to Sonic and the Knights of the Round Table that King Arthur was an illusion conjured by her grandfather, Merlin. She then takes Excalibur's scabbard to make herself all-powerful, so that she can be the new queen.

Sonic and the Knights of the Round Table are forced to flee, and with Nimue's help, they set off to use the Holy Swords to defeat Merlina by putting up a barrier around the kingdom, which is later revealed to be too weak. After the four swords form a barrier around the castle, Sonic is confronted by Merlina, who explains that she knows the kingdom will soon come to an end and wants it to last forever. Sonic fights her, but is outmatched; in the process, Caliburn is split in half, and Sonic takes a very severe beating. Nimue and the Knights observe Sonic's efforts and yell at him to run. Sonic refuses, resolving to stop Merlina no matter what. Sonic's determination, combined with the power of the Holy Swords, repairs Caliburn, and the duo transform into Excalibur Sonic and the true Excalibur, respectively, while Merlina transforms into a monstrous creature known as the "Dark Queen". After a long battle, Sonic and Caliburn manage to defeat Merlina. Though Merlina continues to lament the fate of the kingdom, Sonic gives her a flower and tells her that while all worlds have to end, they simply need to live life to the fullest in the time they have; reminiscing about her grandfather, Merlina takes his advice to heart. Later, Lancelot says that the Knights of the Round Table will have to disband now that King Arthur is gone, but Caliburn reminds them that he is the one who chooses the king; therefore, Sonic is the true King Arthur.
