The lives of Idris and Dimitri, two ordinary teenagers, take a dramatic turn when they discover that Kat, who has recently been fostered by Idris’s mom, is actually a cat-girl with superhuman abilities! She’s been sent to Paloma to work as a Tracker, an undercover operative tasked with stopping other human/animal hybrids (known as Werelings) from using their powers for evil purposes. Having uncovered Kat’s secret, Idris and Dimitri become her teammates.

Together, the three friends go on secret missions to protect Paloma, but also help some of the Werelings they meet find their place in society… all while trying to navigate their own complicated teenage lives.
