After unifying much of Japan, fearsome samurai Oda Nobunaga is dead. His loyal supporter Toyotomi Hideyoshi has launched a coup and seized power for himself. Enraged, powerful General Katsuie has launched his own bid to control the nation.
After defeating Katsuie, Hideyoshi finally ascends to power as the de facto ruler of Japan. Still, Date Masamune, a young daimyo in the north, ignores his missives.

After ending 120 years of civil war and reunifying Japan under his banner, Toyotomi Hideyoshi, the supreme ruler of Japan, lays dead. In a desperate attempt to protect his dynasty, just before his death, Hideyoshi created a council of five powerful warlords. They are to govern Japan until his young son comes of age. But the power hungry Tokugawa Ieasyu declares war on those who oppose him.

As tides rise and fall twice a day, vast amounts of water swirl around the earth. This is a huge energy source that's currently largely untapped. An estimated 3000 gigawatts are available to be harvested globally, enough to power a third of the earth's homes. Yet compared to wind and solar, the technology needed to harness tidal power is still in its infancy. The power of the ocean’s tides is the last great untapped energy source on Earth. From sub-sea kites to floating platforms, teams of engineers are racing to perfect the technology to harness the vast flows of water.

The world's shipping industry is facing a major challenge. If global shipping were a country it would be the sixth largest producer of greenhouse gas emissions. At current growth rates, if we do nothing, those emissions could double or even triple by 2050. But shipping companies and engineers are creating remarkable new machines to make their industry greener, using a resource that has moved man across the world’s oceans for thousands of years…Wind.

A new force threatens our perfect planet. In the past, five mass extinction events were caused by cataclysmic volcanic eruptions. It was not the lava or ash that wiped out life, but an invisible gas released by volcanoes: carbon dioxide. Almost every part of modern life depends on energy created by burning fossil fuels, and this produces CO2 in huge amounts. Humans are changing our planet so rapidly, it’s affecting earth’s life support systems: our weather, our oceans and the living world. The greatest change to be made is in how we create energy, and the planet is brimming with natural power that can help us do just that. It’s these forces of nature - the wind, the sun, waves and geothermal energy - that hold the key to our future.
Through compelling animal-led stories and expert interviews, we discover how CO2 is destabilising our planet. We meet rescued orphaned elephants in Kenya, victims of ever worsening droughts, and join ocean patrols off the coast of Gabon fighting to save endangered sharks. In the Amazon, we witness wildlife teams saving animals in the shrinking forests, and in San Diego we enter a cryogenic zoo preserving the DNA of endangered species before they become extinct.

There had been other pirate settlements in different places but none of them had worked quite the same way that Nassau did. There was a fort there. People stayed, they built a community on the land. Larger and larger numbers of pirate-minded people were showing up there and starting to develop an economy around themselves. Men like Edward Thatch, later known as Blackbeard, his sidekick, Black Caesar, a former slave, and the pied pirate that led them all there, Captain Benjamin Hornigold.
In the second episode, tensions rise between Benjamin Hornigold and Henry Jennings; their rivalry takes a new direction when Hornigold declares Nassau a pirate republic.
