Eighty years after the end of World War II and liberation of the last remaining Nazi concentration camps, correspondent Lesley Stahl reports on the miraculous story of three pregnant women, and their babies, who survived notorious slave labor and concentration camps, including Auschwitz. Stahl meets the three “babies,” now in their 80s, who were born after their mothers concealed their pregnancies from their Nazi captors and gave birth under the most horrific conditions imaginable. The story of their survival, and how they found each other 65 years later, involves seemingly impossible twists of fate, luck, and unfathomable suffering. Stahl also tells the tale of the American medic who was part of the liberation of the camps and discovered, and ultimately helped save, one of the babies. This is a double-length segment. Shari Finkelstein is the producer.

The coastal waters around Cape Town, South Africa had long been a global destination for seeing great white sharks.

Correspondent Anderson Cooper goes to South Africa to investigate a whodunnit that’s fueled a bitter feud among scientists and conservationists who can’t agree on who, or what, is the real culprit. Michael Gavshon is the producer.
