Correspondent Bill Whitaker reports from Germany’s Baltic Coast on the bombing of the Cap Arcona, a little-known human tragedy in the closing days of World War II in Europe. Once a luxurious German ocean liner, the Cap Arcona was commandeered by the Nazis and, at war’s end, turned into a floating concentration camp. Thousands of prisoners were killed in the aerial attack. Whitaker interviews historians and speaks with Holocaust survivors who witnessed the bombing to bring this largely overlooked chapter of history to light. This is a double-length segment. Marc Lieberman is the producer.

Correspondent Jon Wertheim travels to Nottingham, England, to visit the Kanneh-Mason family—seven siblings, all celebrated classical musicians, whose talent is truly music to the ears. Supporting one another in harmony as they take to the world’s stage, this extraordinary septet, as Wertheim discovers, is an orchestra greater than the sum of its parts. David M. Levine is the producer.

Lesley Stahl visits Fred Miller and his family in the large house in southern Virginia that they bought to host family gatherings, only to discover that their own ancestors had once been enslaved on that very property. Miller’s sister and cousins scoured historical records and enlisted a genealogist, who found evidence that their great-great-grandparents, Violet and David Miller, were enslaved on the plantation, then called Sharswood. The dilapidated building still standing behind the main house has been identified by archeologists as living quarters for some of the enslaved men and women on the plantation. Buying this home opened a window into the Miller family’s past that they had never discussed, and that many African American families struggle to obtain. This is a double-length segment. Shari Finkelstein is the producer.

At a moment when American comedy feels under siege, this beloved Dutch theater keeps proving that funny survives—and travels. Michael Gavshon is the producer.

Levine is the producer.
