A mammoth Tsunami strikes the eastern seaboard. It would be a disaster of epic proportions. Some scientists believe this catastrophe could happen one day, but how? This episode shows the Atlantic island of La Palma has collapsed several times in mega-landslides. Another could trigger a tsunami with enough power to cross the Atlantic Ocean and decimate the US East Coast.

90% of the goods we consume in the West are manufactured in far-off lands and brought to us by ship. The cargo shipping industry holds the key to our economy, our environment and the very model of our civilization; without it, it would be impossible to fulfill the ever-increasing demands of our societies. Yet the functioning and regulations of this business remain largely obscure to many, and its hidden costs affect us all. Due to their size, freight ships no longer fit in traditional city harbors; they have moved out of the public's eye, behind barriers and checkpoints.
The film answers questions such as: Who pulls the strings in this multi-billion dollar business? To what extent does the industry control our policymakers? How does it affect the environment above and below the water-line? And what's life like for modern seafarers? Taking us on a journey overseas and oceans, we reveal in an audacious investigation the many faces of world-wide freight shipping and sheds light on the consequences of an all-but-visible industry.

In the last episode, despite disturbing revelations of wrongdoing at Three Mile Island before and after the accident, the utility fights to bring the plant back online. Its Unit 1 had its license temporarily suspended following the incident at Unit 2. Although the citizens of the three counties surrounding the site voted by an overwhelming margin to retire Unit 1 permanently in a non-binding resolution in 1982, it was permitted to resume operations in 1985 following a 4–1 vote by the Nuclear Regulatory Commission.
In 2017, it was announced that operations would cease by 2019 due to financial pressure from cheap natural gas, unless lawmakers stepped in to keep it open. Unit 1 shut down on September 20, 2019.
Billed as the worst nuclear incident in U.S. history, what’s particularly scary here is how close Three Mile Island incident came to becoming a national disaster. Without giving away the whole story, cost-cutting 'solutions' almost cause a catastrophic disaster.

The last chapter explains how the 2010s became another lost decade in the fight against climate change – as the move to natural gas delayed a transition to more renewable sources of energy.
Engineer Tony Ingraffea, in the 1980s, helped develop a new technique for extracting gas and oil from shale rock, which ultimately became known as 'Fracking'. It was to unleash vast new reserves of fossil fuels and was promoted as a cleaner energy source. But Ingraffea explains how he later came to regret his work when he realized that gas could be even worse for climate change than coal and oil.
Dar-Lon Chang, a former ExxonMobil engineer, speaks for the first time on camera alleging that as the company increased its natural gas operations, it was not sufficiently monitoring methane leaks that were contributing to climate change. Now, after a year of unprecedented wildfires, drought and other climate-related disasters, multiple lawsuits are being brought in US courts in efforts to hold Big Oil legally accountable for the climate crisis.

A close examination of the Whakaari / White Island volcanic eruption of 2019, in which 22 lives were lost, the film viscerally recounts a day when ordinary people were called upon to do extraordinary things, placing this tragic event within the larger context of nature's unpredictability and the resilience and power of our shared humanity. The film explores the profound impact on survivors, their unwavering determination to recover and rebuild, and the enduring effects of the eruption.
With remarkable personal stories, stunning visuals, and a poignant reflection on the forces of nature, this documentary offers a gripping portrayal of the human spirit and solidarity in the face of adversity.
