This is a story of a boy who challenges free diving. "Free diving (skin diving)" may remind you of the film "Le Grand Bleu".

The answer lies within "mysterious bond between the sea and human kind". And in the fast evolving world of competitive diving new data emerges that casts light on this bond. (Source: Baka Updates)
