The film chronicles the lives of three mother Pumas (aka Mountain Lions, Cougars) as they survive and thrive in the rugged terrain of Chilean Patagonia. These three matriarchs, Sarmiento, Rupestra and Petaca, drive the dynamics of living and dominating their respective territories. Raising their kits, teaching them how to catch prey and hunting that prey increase these cats’ chances of surviving in this beautiful but challenging habitat.
