Two young fishermen go for some promising fishing on the Baltic seaside. Engrossed in fishing they forget about the weather. At last, having realized the dangerous situation the young men run toward the safety of the shore, but it is too late. They are stopped by a wide gap of water. It is getting dark. Here and there the ice begins to break. Full of fear they stay on the floating ice out in the open sea where they will spend two long nights which will be life changing for one of them.
