The power stone Rex possesses grants him incredible abilities, but at a cost: an animal’s willing sacrifice. For years, he was able to operate under the city's radar until he became the prime suspect in a brutal triple homicide. The truth? He killed three men in self-defence—using the borrowed strength of a Bengal tiger. Now the police and government agencies are hunting him down.

When his coworker Makayla convinces him to help a rhino at the local zoo, they unknowingly disrupt the plans of a dangerous eco-terrorist group. Abducted and forced to join their cause, Rex finds himself trapped between his morals and their ruthless mission. But as he uncovers a far more sinister operation—an underground network trafficking endangered animals—he realizes his power might be the only way to stop it.

To bring down the corrupt elite profiting from suffering and protect the innocent, Rex will have to embrace his primal instincts—even if it means becoming what he's always feared.
