In the high valleys of the Bolivian Andes, the Kallawayan doctors have a unique know-how, legendary throughout all of South America, that has been transmitted from father to son for centuries.
Max is a well-known Kallawayan doctor. Today, he will teach his son Johnny the secrets of the Kallawayan medecine. Together, they travel by foot across the mountains, from village to village to heal those in need.
The Kallawayan ancestral medicine is today threatened. Its safegard will only come from transmission, and thanks to people like Max and Johnny, it has a chance to survive.
