A metempsychosis... of a young scientific reporter in search for the reasons behind the flood of the Chao Phraya, Bangkok's mythical river - finally engulfed by what he thought he could understand and control. Following his hazardous encounter with an Undine, ageless Thai Vouivre of trismegistus hair, he is taken prisoner by water, in the body of a hydrocephalus creature - now hesitating between an endless drowning in the liquid element, and his survival via a suicidal jump in the air... (1) In Bourgogne (France), the Vouivre (Wyvern) is a chimera, mi terrestrial mi aquatic, living by the eponymous river.
