Lety documents an action which took place in May 2009 involving František Ďuďa and Martina Ďuďová, two Slovak Roma singers. The action consisted in visiting a commemoration for the victims of the concentration camp at Lety, in the Czech Republic.
During the Nazi occupation Lety was the prison for 1,309 Roma, most of whom were later transferred to the Auschwitz-Birkenau extermination camp. Since the 1970’s the site of the Lety camp has been used as an industrial pig farm. For this reason, the commemoration is held in a nearby woodland clearing.
