Keelin, Vlad, and Wilko are invited to attend the Kristalceremonie in the Elfenrijk.

Three youngsters possess each individually a unique and special talent, in which they can transform in fantasy creatures. Keelin, the elf; Vladimir, the vampire; Wilco, the werewolf. Together they form the Nightwatch, a secret group that protects the people of Schemermeer from mystical and dangerous creatures.

Vladimir, Wilko, and Keelin are summoned by the High Council, expecting to be honored. Instead, Xantara, the Council’s president, accuses them of a grave mistake and destroys their symbols, stripping them of their powers. Soon, they discover her true plan: using their stolen powers and the Crystal of Evil to destroy the human world. Powerless but determined, the Nachtwacht must restore their symbols and stop Xantara before it’s too late...

Vlad, Keelin, and Wilko find themselves in the realm of werewolves. Here, Wilko's father, Lupino, has united the wild werewolf clans in peace. Together with Wilko's sister Rhea, he wants to usher the werewolves into the modern age. However, he is opposed by a few who want to return to the law of the jungle. During a dark sacrificial ritual, they create the Blood Moon, an eternal solar eclipse that makes the werewolves ferocious and wild.

Meet Keelin, Vladimir and Wilko, also known as The Nightwatch, a secret covenant with only one purpose: fight the evil from the underworld.
