Episode 1: Fall of the Leaning Tower
Even before it was finished 800 years ago, the Leaning Tower of Pisa - a masterpiece of medieval architecture - began to topple, shaken by earthquakes and sinking slowly into the unstable soil. Today, the top hangs just 16 feet over the base and collapse seems imminent. NOVA follows a decade-long search for a solution to correct the lean and save the unique building. State-of-the-art computer models, ingenious experiments with models and a string of near-disasters eventually push an international committee of prominent engineers and architects into an 11th-hour decision. A suspenseful tale of engineering hopes and frustrations, the program is both high comedy and a hands-on engineering adventure, guiding viewers into the minds of daring medieval architects and their ingenious modern successors.
Episode 3: The Killer's Trail
The death of Marilyn Sheppard in 1954 is one of the most famous unsolved murders in America. The indictment of her husband, Dr. Sam Sheppard, quickly became the "Trial of the Century," then the "Re-Trial of the Century," making a celebrity out of lawyer F. Lee Bailey. Although most of the forensic evidence gathered in 1954 was ignored during Sheppard's trial, it is being re-examined with today's advanced technology. Like an intricate puzzle, the clues come together to overturn previous assumptions about the killer and point to an entirely new suspect. NOVA assembles a notable team of experts—including Barry Scheck, a well-known lawyer from the O.J. Simpson trial—and builds a precise replica of the Sheppard house, complete with the original furniture. With this unique revisiting of a vanished crime scene, NOVA investigates a horrifying and sensational milestone in forensic science.

Episode 4: Island of the Spirits
In the far north of Japan, thrust out into the north Pacific, is the remote island of Hokkaido. It's a land of towering volcanoes and steaming lakes, marshy valleys and fairy tale forests. Among this magical scenery, where summers are brief and winters are fierce, lives an extraordinary spectrum of life, found nowhere else in Japan. Here among the coastal lowlands, grizzly bears plunge into icy streams for salmon, Japanese cranes perform balletic courtship dances to one another, the rare and enormous Blakistons fish owl swoops on flying squirrels, and white-tailed eagles scan the rugged ocean cliffs for unsuspecting seabirds. HIgh on the mountains Asiatic pikas, arctic hares and Siberian chipmunks gather food, ever-watchful for the predatory sable. We think of Japan as a highly-populated, ultra modern society, and yet it remains a highly spiritual place where wildlife is treasured and carefully protected. Weaving Ainu legend with fascinating natural behavior, this film will follow the lives of Hokkaido's special creatures through the seasons, to capture the true essence and beauty of this other-worldly place.
Episode 5: Decoding Nazi Secrets
Most historians agree that by enabling Allied commanders to eavesdrop on German plans, Station X shortened the war by 2 or 3 years. Its decoded messages played a vital role in defeating the U-boat menace, cutting off Rommel's supplies in North Africa, and launching the D-Day landings. Now, for the first time on television, a 2-hour NOVA Special tells the full story of Station X, drawing on vivid interviews with many of the colorful geniuses and eccentrics who attacked the Enigma. Wartime survivors recall such vivid episodes as the British capture of the German submarine U-110; one of its officers describes how he saved a book of love poems inscribed to his sweetheart but failed to destroy vital Enigma documents on board. "Decoding Nazi Secrets" also features meticulous period reenactments shot inside the original buildings at Station X, including recreations of the world's first computing devices that aided codebreakers with their breakthroughs. Station X not only helped reverse the onslaught of the Third Reich, but also laid the groundwork for the invention of the digital computer that continues to transform all our lives.
Episode 6: Voyage of Doom
Buried in mud beneath the shallow waters of Matagorda Bay in Texas, lay a glorious remnant of one of the most ill-fated voyages of the Age of Discovery. After years of searching the area, nautical archaeologists doing a magnetometer survey honed in on a promising site. And on the first day of diving, they were astounded to feel the distinctive outlines of a cannon, and sense the massive size of the wreck. When the cannon was hauled from the water, their hunch was confirmed: This ship, called La Belle, belonged to the 17th Century French explorer Robert Cavelier de La Salle. NOVA follows the building of a coffer dam and subsequent complete excavation of this remarkable site. Preserved were not only armaments and trade beads, but also a wealth of organic material—the wooden hull, leather shoes, and even a skeleton—that brings the voyage to life.
Episode 7: Electric Heart
The program tells the story of a handful of brilliant, obsessed surgeons and researchers who have pursued the target of a practical artificial heart for decades.
Episode 8: Tales from the Hive
NOVA chronicles a year in the life of a bee colony with stunning images that take viewers inside the innermost secrets of the hive. The documentary team spent a year developing special macro lenses and a bee studio to deliver the film's astonishing sequences. These include the "wedding flight" of the colony's virgin queen as it mates in mid-air with a drone; the life-and-death battle between two rival queens for the colony's throne; and the defeat and death of a thieving wasp at the entrance to the hive. The show also explores such mysteries as the famous "waggle dance" with which scout bees signal the exact direction and distance of nectar sources to the rest of the hive. A vivid picture emerges of the bee's highly organized social life, revolving around the disciplined sharing of construction tasks, the collection of nectar, and warding off enemies. "Tales From the Hive" pushes the boundaries of wildlife filmmaking and opens up an unforgettable window on a strange and complex insect world.
Episode 9: Lost on Everest
The program chronicles a successful 1999 NOVA expedition to investigate the mysterious disappearance of George Mallory and Andrew Irvine high on Everest in 1924. During this expedition, which included a NOVA/PBS Online Adventure, Mallory's body was found, though the mystery only deepened.
