Lynn Sherr, the award-winning correspondent for ABC TV’s 20/20 newsmagazine, went to Africa for the first time in 1973 and fell in love — with giraffes. “They were a dazzling, unexpected revelation: gawky, graceful anomalies; cool, gentle giants dressed in golden, stained-glass coats. And when they ran, they seemed to float. I was hooked.” Journey to Kenya and South Africa, and to an American zoo that is the giraffe breeding capital of the Western Hemisphere, for a revealing look at this powerful, captivating creature when Ms. Sherr hosts Tall Blondes.

Lynn Sherr hosts a collection of clips highlighting memorable moments from the program's first 25 years. Also: a tribute to the series' creator and host George Page, who died in 2006. Included: hatchling sea turtles on a Caribbean beach; barnacle goslings in the Arctic; a wildebeest defending her calf from wild dogs on the Serengeti; crocodiles attacking gazelles; chimpanzees saved from medical testing; a reunion of two elephants after 25 years apart.
