The Saturdays are a family of scientific explorers dedicated to protecting the secret artefacts and crypts of the world. To the Saturdays, ordinary folk-tales aren't just legends but real-life mysteries and adventures: from the Gobi Desert to the Marianas Trench, they explore ancient temples and bottomless caves and tangle with twisted villains. But at the end of the day, the Saturdays and their hyper-exotic pets Fiskerton, Komodo and Zon are just a warm, loving family getting through everyday growing pains and squabbles.
Six months after the events of “Kur Rising,” everything has changed for the Saturday family. The Secret Scientists are tracking Zak down to take him into custody, forcing the Saturdays into life as Airship-based fugitives.
Returning home to their demolished HQ to gather up some old Sumerian tomes from Drew’s library, the Saturdays are ambushed by Tsul’Kalu, the great hunter and previous owner of the Hand of Tsul’Kalu on the end of Zak’s Claw.
Doc, Zak and Fiskerton strike a bargain with the Secret Scientists. If the Saturdays can subdue a huge, wild cryptid that’s gotten loose in Dr. Beeman’s Peruvian lab, the Scientists agree to call off their pursuit of Zak for six months.
