When their mother dies, Swiss brothers Thomas and Erik undertake the mammoth task of cleaning out her junk-filled apartment. Sorting through seven dumpsters' worth of accumulations, the men piece together an unbelievable family history. The long and twisted tale -- as revealed in this enthralling and darkly comic documentary -- is replete with elite nobles, sordid affairs, Nazi officers, nymphomania and even a photo cameo by future U.N. chief Kofi Annan.
