Nadie, a tough bounty hunter, captures the amnesiac Ellis, a prime suspect in a scientist's murder. Instead of delivering Ellis right away, Nadie decides to escort her to Wiñay Marka, a place rumored to unlock Ellis's memories. Despite this detour, Nadie warns Ellis that she will face consequences once her past is revealed. Guided by Ellis's link to the Inca Rose gemstone, the duo embarks on a quest towards the enigmatic 'Eternal City' in the south of Mexico.
