EW.COM – If you thought your life was complicated, you should really talk to Clary Fray. The protagonist of the upcoming series Shadowhunters, based on the Mortal Instruments books, discovers on her 18th birthday that not only is there a Shadow World full of supernatural beings, but she’s a half-angel, half-human who’s destined to protect the world from demons. Or at least, that’s where her journey begins.

For the rest of the story, we turned to Shadowhunters cast members Katherine McNamara (Clary Fray), Dominic Sherwood (Jace Wayland), Alberto Rosende (Simon Lewis), Emeraude Toubia (Isabelle Lightwood), Matthew Daddario (Alec Lightwood), Isaiah Mustafa (Luke Garroway), and Harry Shum Jr. (Magnus Bane), who attempted to describe the plot of their show in 30 seconds.

Shadowhunters premieres Tuesday, Jan. 12 at 9 p.m. ET on Freeform.
