The war on drugs was upon them, and despite believing that they were untouchable, the authorities close in. The 'Cowboys' are left with three options: flee, flip or face the music. Falcon and Magluta, along with their associates, were ultimately arrested and tried for their crimes. But they won't go down so easily.

As Sal has his day in court -again- Willy decides to go his own way. After two decades, can the government finally make the charges stick?

The series, depicted by state of the art CGI techniques, and applying the laws of life on Earth to the rest of the galaxy, blends fact with science fiction and conceptualizes what alien life might be like on other planets.
In the prologue, astronomer Didier Queloz makes an appearance to discuss the discoveries of exoplanets and how they are analyzed in the real world. In Episode 1, the fictional world imagined is Atlas, a world with higher gravity than Earth and a thicker atmosphere leading to airborne creatures. In explaining the aliens of Atlas, the episode also explores the handicap principle in insects, and shows a rehabilitative form of falconry as captive falcons are trained to live in the wild.

Predators and prey are in an arms race for survival. Hunters and hunted deploy hidden super- skills in the battle to eat or be eaten. Masterclasses in predatory perfection are vital to passing on skills. So when they're ready to hunt for real, the next generation is fully prepared for the battle between predator and prey.
Life is a mission, survival. Animals have evolved secret weapons and hidden skills to outsmart their enemies. So in those life or death moments, it takes the most extraordinary super powers to prevail.

Sal takes uncharacteristically desperate measures in the face of new federal charges, an unearthed paper trail and increasing pressure on a confidant.

This episode discusses the human exploration of Antarctica, in particular the mission led by Captain Robert Falcon Scott, whose team died on the way back from the South Pole. It shows the scientific work in the modern human bases in Antarctica, especially Mawson Base and its observation of Adelie Penguins (partially through tracking devices). The second half of the episode describes how the series was made. Most crucial was of course the camera work. To get access to the wildlife of the sea, for example, boats, divers, suspended capsules and remotely controlled cameras mounted on inflatables were used. Particularly dangerous to divers were Leopard Seals and other predators. The film concludes that although working in Antarctica is now much easier than during the early days of exploration, human footsteps on the continent are still exceedingly rare in part because of international treaties prohibiting industrial exploitation.
