It's a quiet life, until a local eccentric known as Spooky Ed shows up on their doorstep. Ed entrusts Jeffy with hiding a strange and dangerous object, something he calls "the key to everything', and tells Jeffy that he must never use the device. But after a visit from a group of ominous men, Jeffy and Amity find themselves accidentally activating the key and discovering an extraordinary truth.
