Something is brewing in the town of Whitby. To best friends Lil and Verne, it just seems like a particularly bad storm. But Cherry Cerise, the last of the Whitby witches, fears that ancient forces are at work, reviving the curse of a long lost magical artefact. The legend goes that the Nimius was created by magician Melchior Pyke, with the assistance of a young witch known as Scaur Annie. But they were both betrayed by Pyke's villainous manservant, Mister Dark, causing a feud that has survived even beyond death. As Mister Dark, with his horrific winged familiar, arises to mastermind Whitby's very own apocalypse and take the Nimius for his own evil purposes, can Lil and Verne join with Cherry to quell his plans and save their home.
