Valentina, a werewolf girl born with a Primordial bloodline, had her wolf bone cut out alive by her biological father and transplanted into her younger sister, leaving her reduced to a cripple. Matteo, the Moretti Alpha, witnessed the torture years ago, spent five years searching for her, and bound them to each other with a blood oath. The family council of elders upholds the ancient doctrine of exterminating Primordials, while the various factions plot against one another. During the trial, the female lead’s wolf bone returns to its rightful place and she awakens her power, entering bloodline symbiosis with Matteo; she resolves her sister’s hatred and settles scores with all the villains. At the end of the season, a vengeful woman from another Primordial bloodline appears, and a new crisis descends.
