Six months after the Kur crisis, the other Secret Scientists have discovered that Zak is Kur, and are tracking him to take him into custody, forcing the Saturdays into a life as fugitives. To make matters worse, the Nagas are also after Zak, in hopes of making him their new leader. Meanwhile, Doyle and Zon go to England and have a run-in with Leonidas Van Rook (who had just had his buisness overtaken by Abbey) when looking for V.V. Argost, who has mysteriously disappeared.
