During one year, Antony Colas worked on an unknown tidal bore in Sumatra Forest. For millennia, this wave has broken along 40 kilometers in the National Park.

In September 2010, four French surfers - Antony Colas, his brother Fabrice, Patrick Audoy, Eduardo Bagé, and cameraman Maxence Peyras - decided to discover this deep land.

The goal: to surf this incredible wave for the first time. "Bono" is the story of the expedition.
