In the second episode, Will Smith descends 3,300 feet to the bottom of the ocean in a deep-water submersible, where even fewer people have gone than outer space. Along the way down, Will and explorer Diva Amon investigate how colour is used in the natural world and the role of bioluminescence. In the oceans, nearly 80 percent of animals use bioluminescence in some way, possibly the most common form of communication on the planet.

By August 1949 the USSR became the world's second superpower, thanks to its spies who had stolen America's atomic secrets. But by March 1953, Stalin is dead and KGB chief, Beria, is executed later the same year. Nikita Kruschev tries to reduce the power of the security service, splitting it into several sections...but it doesn't last and, soon, the KGB is back.
In the USSR, countless KGB operatives spied on opponents of the regime at home, guarded the state and party leadership, and abroad tried to find out as much as possible about the intentions of the NATO countries and, if possible, to sabotage them.

As World War II drags on into another bitter winter the Allies become desperate to end the conflict. Winston Churchill turns to his formidable bomber force to break the deadlock.
The population of an eastern German city is caught in a devastating firestorm and harnessed by the Nazis; the controversy turns the Allies on themselves.

Ricciardo is still trying to get to grips with that pesky papaya number, whilst things get tetchier and tetchier between the Macca team-mate as races go by. 'We’re very different,' says Norris darkly. Luckily there's a sprint race for Ricciardo to get his Mansell-esque chops into, then it all falls into place. Bottas gets a grid penalty, Verstappen and Hamilton waltz off the track together and Norris promises not to overtake the old man in front a la Damon Hill / Ralf Schumacher at Spa ’98. The Honey Badger is back!

(Click CC for subtitles) Rumors fly about whether an up-and-coming driver will join Hamilton on team Mercedes, potentially leaving Valtteri Bottas without a seat. Seemingly permanently stuck in the crisis of a one-year contract running out, this time Bottas has Mercedes golden boy George Russell breathing down his neck. The young Brit desperately wants Bottas’ seat, and things come to a head when the two collide at Imola. Scandalous.
Bottas can’t resist the inevitable though, and after Russell puts the F1 on the front row at Spa, whilst the Finn can only manage eighth, it looks to be all over. Thus follows a scene of Russell being told he has the Mercedes seat by Wolff in a scene which looks so staged it would make even cringe.

We learn as much from victory as we do from loss. We employ strategies to gain the advantage, unconventional methods to overwhelm adversaries. One dedicated force steeped in mystique has always been part of war. Special operations, elite and unseen. Their presence felt by lethal attack. From the biblical era to the future of warfare, the battle environment is reshaped and redefined by special operations. Special Operations soldiers have come out of the trenches and are entering new domains of warfare.
