On thin ice è un breve documentario su quattro ragazzi che hanno deciso di fare skate sulla sabbia gelata delle spiagge norvegesi.
Jørn has a dream; The most absurd so far. A dream that actually fits him superbly. He is a filmmaker, nature lover and skateboard enthusiast and what would fit better then to make a skateboard film staged on a frozen beach in Lofoten surrounded by high mountains and meter long waves? And that's not all; He will gather the best skaters from Norway and give them the opportunity to skate the world's first ramp made out of just sand and water. Totally dependent upon the weather, the project is on thin ice when confronted with the Northern storms.
