Based on the six best-selling young adult fantasy book series, Shadowhunters follows 18 year old Clary Fray, who finds out on her birthday that she is not who she thinks she is, but rather comes from a long line of Shadowhunters — human-angel hybrids who hunt down demons. When her mother Jocelyn is kidnapped, Clary is thrown into the world of demon hunting with mysterious Shadowhunter Jace and her best friend, Simon.
