In 1993 , NYPD officer and caving enthusiast Chris Nicola visited Ukraine to explore the Verteba and Priest 's Grotto caves , and found evidence that they had recently been inhabited by humans . After discovering that the caves were used by three Jewish families ( Stermer , Dodyk , and Wexler ) , comprising 38 people , led by matriarch Esther Stermer ( 1888 – 1983 ) , escaping The Holocaust , he embarked on a decade-long quest to find survivors . The film features interviews with some of the 36 survivors and/or their descendants , now living mainly in New York City and Montreal . It includes a segment in which Tobias brings some of the survivors , the oldest of whom was a nonagenarian , back to the caves
