This episode investigated the cause of the Tunguska event. The programme concluded that the explosion was caused by the impact of a comet fragment, or other ice-rich body, that exploded above the ground. The reasons given for this were the fact that there was no crater as might be expected had a stony or iron object been involved and the heightened levels of rare earth elements discovered in the devastated environment afterwards.

This episode is divided equally between considering evidence for the Bigfoot and Yeti. Interviewees for the segment on the Yeti include Don Whillans, Lord Hunt and Eric Shipton. Lengthy consideration is given to the Patterson-Gimlin film, and interviewees include Grover Krantz - who demonstrates several casts of alleged Bigfoot tracks that he feels bolsters his belief that the creature represents a relative of Gigantopithecus. Clarke concludes that, although Russian scientists who studied the Patterson-Gimlin film declared the stride to be 'quite inhuman', special effects used in the 1968 movie "2001: A Space Odyssey" showed that it is possible to create very convincing ape-men. He also notes that it would be very difficult for a creature such as Bigfoot to remain undetected in North America.

This show is concerned with technology from history that was either ahead of its time and subsequently forgotten, or artefacts which are mysteries in themselves. This includes the Baghdad Battery, where German scientist Arne Eggebrecht is shown electroplating a small silver statue with a gold cyanide solution and a replica of the battery using grape juice. There are also segments on the Antikythera Mechanism (including an interview with Derek J. de Solla Price), the Stone Balls of Costa Rica and the so-called 'Skull of Doom' which famously dominates the opening credits of the series. Also included are the vitrified stone forts of Scotland including Tap o' Noth near Aberdeen. Clarke opines at the end that had some of these forgotten technologies been developed and not lost that we would have 'colonised the stars' by now.

Including the giant squid, giant octopus and megamouth shark.

This episode introduces the themes that are explored in the remainder of the series. Clarke expounds on his categorisation of mysteries, self-consciously aping the famous 'close encounters' categorisation used by some ufologists: Mysteries of the First Kind — phenomena which were mysterious to our ancestors but are now well understood. Clarke illustrates this category by observing the solar eclipse of February 16, 1980 from Hyderabad, India, highlighting the fact that eclipses are still treated with reverence and suspicion in some cultures. Mysteries of the Second Kind — phenomena which are as yet unexplained, but where we have several clues that hint at an answer. Clarke looks at ball lightning (including one sighting by Roger Jennison in the cabin of an aircraft), the Loch Ness Monster, Remy Van Lierde's encounter with a gigantic snake, a sighting of a sea serpent off the coast of England, the stone spheres of Costa Rica, the Baghdad Battery, the vitrified forts of Scotland, Stonehenge, and the Cerne Abbas Giant. The ruined ancient palace of Sigiriya in Sri Lanka, which Clarke mentions at the beginning of the episode, could also be included in this category.

King Arthur is the greatest of British literary heroes, celebrated by poets and writers for over a thousand years. From the twelfth century to the twentieth, his exploits have been celebrated in prose, verse, film, video games and comics. But is the story of King Arthur true? Legend describes him as a gallant and noble warrior. With the guidance of Merlin the magician, he leads the people of England to victory and freedom. He marries a beautiful and elegant Cornish woman name Guinevere and together, they rule from Camelot. But war continues for the young Arthur and he is forced to establish his knights of the round table, men willing to fight for Britain's independence. Are these tales merely myth or is there some substance to the legend?
