Set against the backdrop of feudal Kerala, the mysterious criminal and vigilante, known simply as Odayan, slowly amasses wealth and power through subterfuge and brute force, and builds himself a criminal empire that ultimately challenges the reign of the Zamorin himself. His real intentions remain unknown, but the man behind the green face paint proves himself a master of arcane arts and a savant of Kalaripayattu, as the Zamorin tries to pit his best masters against Odayan and prevent this mysterious foe from garnering support and destabilizing the Zamorin’s reign.
