In the new international trailer for "The Mortal Instruments: City of Bones," our hero, Clary Fray (Lily Collins), has just learned she's "not a mundane" (slang for human), but a Shadowhunter, a group of half-angel warriors who've worked for centuries in secret to protect the world from demons.

"Welcome to the City of Bones," says Jace Wayland (Jamie Campbell Bower), a fellow Shadowhunter.

Needless to say, she's a bit freaked out.

There's a lot of action in the clip, as Clary adjusts to her new reality, including seeing Jace and other Shadowhunters when no one else can, and learning her recently gone-missing mother (Lena Headey) is also a member of the group. As Clary falls deeper into the Shadowhunters' world, she learns she's joining the cause just as "humanity is on the very brink of extinction."

Based on the books by Cassandra Clare and directed by Harold Zwack, "The Mortal Instruments" is due in theaters August 21 -- two days earlier than originally planned.
