Rember Yahuarcani is an indigenous artist from the Uitoto Nation who lives in Lima, Peru. From his clan, the White Heron, only two families remain in Peru. Rember's paintings are inspired by the stories his grandmother Martha told him before she died. However, he has never dived into the darkest part of his nation’s history: the indigenous massacre during the rubber boom. Martha is a survivor of the horror and she speaks to Rember in dreams guiding him in a spiritual journey back to the jungle. He first visits his parents, who are also artists, in the Peruvian jungle. And finally, he sails to La Chorrera, in Colombia, where he confronts the past and meets other members of his clan.

Las Pollas del Metal (The Metal Dicks), a heavy metal band, are on tour to promote their first album. On the road to Galicia, their van suffers a flat tyre and they have to stay overnight at the "Gutierrez's town", a small village located nowhere. Next day, the town is throwing a festival where its inhabitants celebrate the patron saint's day. The Mayor invites the artists to join the celebration and they accept, without knowing a brutal danger awaits them.
