Years after a violent war destroyed much of the world, Kaspar has grown up in a society based on peace and harmony.
But beyond the city walls, a vicious band of rebels are plotting to tear this peace apart.
It is up to the Guardians - an elite peacekeeping force - to protect the city, without ever resorting to the brutal methods of their enemy.
When Kaspar joins the Guardians, he has a chance encounter with a rebel - a beautiful girl named Rhea.
Haunted from that moment on by strange visions and memories - memories that could only belong to Rhea - he realizes he hasn't been told the truth about what the rebels really want, and what he's really fighting for.
