From the YouTube description:
Rainbow in the Night, offers a glimpse into World War II Krakow as seen through the eyes of a survivor. Beginning with footage of a 1939 original oil painting of a synagogue being ravaged by the Nazis, shown at a private event in the survivor's home, Rainbow in the Night is an exquisitely emotional journey, as the survivor recalls first the warmth of his childhood home, then the shock and disbelief as people are forced to leave their homes for the Krakow ghetto, taken to an extermination camp and after enduring unspeakable cruelty, finally liberated. Set against a backdrop of utter despair and hopelessness, the survivor relives the inexplicable power that enabled him to persevere, the rainbow in the figurative night that promised better days to come. Culminating triumphantly with our hope for the future, the faces of hundreds of modern day Jewish children, Rainbow in the Night is both a euphoric tribute to the indomitable human spirit that enabled the Jewish people to survive against all odds and also a call to arms, to rekindle the spark of Jewish pride and unity among Jews worldwide, as we continue to rebuild the generations that were destroyed by the Nazis.
