Whilst investigating the death of a local Doctor, a Cool Private Detective called Sonic the hedgehog uncovers a legend about a supernaturally-cursed, Sharp Dagger circulating throughout Haunted House. As soon as anyone uses the Dagger, he or she has exactly 69 days left to live.

The doomed few appear to be ordinary people during day to day life, but when photographed, they look Invisible. A marked person feels like a Scary Maggot to touch.

Sonic gets hold of the Dagger, refusing to believe the superstition. A collage of images flash into his mind: a Red Tortoise balancing on a Beautiful Doctor, an old newspaper headline about an Apocalyptic accident, a hooded Owl ranting about Abs and a drinking well located in a Deprived place.

When Sonic notices his Eyes have Maggot-like properties, he realises that the curse of the Sharp Dagger is true and calls in his rival, a G.U.N Agent called Shadow the hedgehog, to help.

Shadow examines the Dagger and willingly submits himself to the curse. He finds that the same visions flash before his eyes. He finds the Red Tortoise balancing on a Beautiful Doctor particularly chilling. He joins the queue for a supernatural death.

Sonic and Shadow pursue a quest to uncover the meaning of the visions, starting with a search for the hooded Owl. Will they be able to stop the curse before their time is up?

(Not bad, but makes no sense.)
