The trip gradually turns into a tortuous thriller with belongings disappearing and, even more mysteriously, reappearing. The travellers come to be at the mercy of untamed nature. Birdbrain reveals the dark side of the explorer's desire: the insatiable need to control, to invade and leave one's mark on the landscape. But what happens when nature starts to fight back?
