On a freezing cold winter day, several guests visit their relatives in an old people's home in the Frankfurt area. When the weather changes shortly afterwards and black ice falls over the area, the guests unexpectedly get stuck.
Soaked to the skin, Costantino sinks into the haystack like old timber left on the shore by a stormy sea. Torrential rain has just put out the fire that in a single night ravaged Assandira, a farmstay deep in the woods of Sardinia. But the rain hasn't quenched the pain, the endless remorse for the son lost to the flames, the son he was unable to save. The first to arrive are the carabinieri and the young investigating magistrate: Costantino tries to tell them what happened the previous night, to explain how it all began.
