Shadowhunters is an American supernatural drama television series developed by Ed Decter, loosely based on the popular book series The Mortal Instruments written by Cassandra Clare. It premiered in North America on Freeform on January 12, 2016. Primarily filmed in Toronto, Ontario, Canada, the series follows Clary Fray (Katherine McNamara), 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.
It is the second adaptation of the novel series, after the 2013 film The Mortal Instruments: City of Bones, which like the series was produced by Constantin Film. The debut season of Shadowhunters has received mixed responses from critics. The pilot episode attracted the largest audience for Freeform in more than two years. The show has received numerous award nominations, winning one GLAAD Award and two Teen Choice Awards.
