In the border forest shrouded in the shadow of the wolf clan, the young hunter Ash survives alone relying on her calmness, agility and superb combat skills. During a mission to hunt down a ferocious white wolf, she unexpectedly encounters Kael, a mysterious man concealing his identity — a half-blood werewolf with wolf clan blood, yet being hunted down by his own kin.
To uncover the truth and take revenge on the enemies who destroyed their homeland, Ash and Kael are forced to team up, gradually growing from mutual-distrusting strangers to each other's most vital support. Amid the perils of the wolf clan's pursuit, hidden identities and the curse of fate, the two must face a cruel choice: whether to become a victim of hatred, or to break the shackles of bloodline and destiny together.
