During an insurgency in India, treasure hunter Chloe Frazer sets out to recover the fabled Tusk of Ganesh, an artifact her late father died searching for. To reach it she partners with the hardened mercenary Nadine Ross, and the two slip past the forces of Asav, a ruthless warlord who wants the relic to rally the country into civil war. Following a trail of clues through the mountains of the Western Ghats toward the ancient Hoysala Empire, the pair must rely on each other's very different skills while staying ahead of Asav and his men.
