new movie from Icelandic director Baltasar Kormákur (for example his well known epic movie 101 Reykjavik).
it is true story about sailor who survived capsizing his fishing boat, then swimming 6 hours (six hours)!!! in ice cold ocean back to the shore. it is still mystery how he made it.
for example human being is able swim (or be) in near zero degree water about 2 minutes then his heart is stopping.
