Kepa Junkera left the stage on the 6th of December of 2018 in Ghent, Belgium. He vanished, his accordion went silent. The news mentioned a stroke, an urgent admission to hospital, a recovery process, and then nothing. The self-taught Basque artist who had elevated the trikitixa and the popular Basque music to their highest level, who had released an album almost every year during his 40-year career, disappeared without a trace.

Driven by a passion for history and the weight of an absence, a professor, and a relative of a deportee who disappeared during World War II begin an investigation across Europe to uncover his fate. This quest soon leads to an extraordinary discovery: the story of František Suchý and his son, who, defying the Nazi regime, managed to preserve the names and ashes of more than 2,200 victims. Among them, the long-lost remains of that deportee, whose trace was erased eighty years ago.
