In 1850, Alfred Russell Wallace investigates the island world of the malayan archipelagos - and discovers that the nature there is separated into two parts through a mysterious magical border. A border which still bears his name: The 'Wallace-Line'. 150 years later, a new generation of investigators travel to the mysteries Wallace-Line to investigate under water. They dive down to a mystical world, a world in which Wallace was never able to get into. The investors want to find out if a 'marine' Wallace- Line exists.
