This documentary gets inside the world of the most fearsome indians of the Amazonia, the so called Korubo. The cameras will be able to shoot for the first time the daily life of this secret Brazilian tribe. Feared by the nearby tribes, they are known as "Head crashers" by the white colonists because of their extraordinary ability to make use of huge sticks. This tribe has suffered a real persecution for many years. Our crew made a great effort to gain the confidence of these unpredictable natives. An unplanned fact made easier the approach to the fearsome tribe. The documentary will show how their queen Maiaá, who was suffering malaria, could be saved by us. The gratitude allowed our cameras to shoot their daily life including amazing moments such as the electric fish hunt or enjoying the children's games. A journey to the heart of this people and their fight for survival.
