The future, our world... After years of health, economic and ecological crises, a global civil war breaks out, ignited by a huge pharmaceutical and political scandal denounced by the activist group C.H.A.O.S. 15 years later civilization has recovered, divided between large urban centres, under military and medical surveillance, and freer rural areas, where those who refuse this system of health control take refuge. It is in this divided world that Beck sets out in search of her mentor Kal, who has been missing for several days. This quest leads the young orphan to the town of Bajara, known, among other things, for its free-fighting competitions.
