When an exhibition of ancient Egyptian relics comes to the British Museum, an anomaly opens in a mysterious monument called the Sun Cage. A creature emerges from it - a Pristichampsus, a kind of monstrous crocodile that can run on two legs.
This creature, which comes from a past much more distant than the Egypt of the Pharaohs, somehow became worshipped as a God in that civilization, and is now portrayed in the hieroglyphics on the Sun Cage. The murderous creature wreaks havoc in the museum before escaping into the city.
Helped by Sarah Page, the smart and surprisingly sexy archaeologist at the museum, Cutter and the team (Abby, Connor and their new Head of Security, Captain Becker) set off to track down the creature down before it hits the streets of London.
Along the way, Connor begins to believe in a legendary curse attached to the monument (in the style of Tutankhamen) and convinces himself he is next in line for the crocodile God's revenge.
