This portfolio of films invites us to discover one of the longest rivers in the world, the Mekong. All along its course, from the Tibetan plateau to its mouth in the China Sea, on nearly 5.000 kilometres, this mighty river offers us uncountable enriching discoveries: the wonderful flora and rich fauna, the diversified landscapes of the Greater Mekong, the majestic mountains and wild gorges, the quiet lakes and breathtaking waterfalls. We will discover countless temples set on its banks revealing the presence of Buddhism but above all, we will meet some of the 320 million people who live along the stream. It spreads over six countries: China, Burma, Thailand, Laos, Cambodia and Vietnam. With its abundant production of rice, fruits, vegetables and flowers, its basin has become what could be called the garden of the world, in comparison to Amazonia which is often called the lung of the world.
