Zak Saturday realises he has a gift for discovering Crypids, so when he learns of Argost's evil plans, he must convince his parents to let him join the team.

The Saturdays race to recover the last hidden piece of the Kur Stone, which Argost wants to use to control the world.

The Saturdays try to stop Hibagon, a bigfoot implanted with the brain of a well-meaning scientist, from taking revenge on the crime lord who created him.

Secret Scientist Dr Paul Cheechoo and his team accidentally disturb a summoning chamber, unleashing both a violent snowstorm and a wolfish Amarok.

When Doc and Drew go out to celebrate their anniversary, Zak chases away the babysitter only to learn that the Saturday headquarters is being stalked by a cryptid-devouring foe.

When the sunken city of Kumari Kandam mysteriously resurfaces with a new leader, Zak takes charge of restoring the proper ruler to the throne.
