In the third episode, the discovery of extraterrestrial life might face an impossible challenge: the physics of the universe itself; but using cutting-edge tech, experts might be on the verge of a groundbreaking find -- and the evidence could already be in hand.

Brian Cox looks at our attempts to answer one of the most profound questions we can ask – are we alone in the universe? With scientists sending space probes to the furthest reaches of our solar system and beyond, the scientific search for alien life has begun. Inspired by a childhood love of science fiction, Brian still hopes to hear from ET. In this film, he explains why this search deserves to be taken seriously, and he explores the chances of it happening.

As their high-profile trial begins, Willy and Sal attempt to neutralize witnesses against them in a variety of ways — some legal, others not so much.

In 2011, a Social Security lawyer named Eric C. Conn and a judge named David Daugherty were investigated for committing massive fraud over many years. Conn figured out that he would get paid a hefty retainer for every Social Security disability payment he managed to get approved, so he and Daugherty (who need quick cash to pay for his daughter’s upcoming narcotics trial – which presumably meant bribing an awful lot of people) came to an arrangement.
In the second episode, Investigators starts to collect evidence against Eric and Judge Daugherty. The whistle-blowers are pressured.

Magic mushrooms, long considered sacred by the Indigenous Mazatec in Mexico, become the subject of scientific studies measuring the intense effects of its Psilocybin and its potential therapeutic use.
In the second episode, we are introduced to Ben, who’s battled with crippling Obsessive-Compulsive Disorder (OCD) his entire life. When he had his firstborn, Ben’s life became full of panic attacks regarding his son’s safety, and he knew something had to change. Ben signed up for a psilocybin-assisted therapy clinical trial which was testing whether the psychedelic could help people with severe OCD. In the session under the influence of psilocybin, Ben felt decomposed and eventually grew into a tree. While living as a tree, he saw his human self, playing with his child. Though this sounds scary, from Ben’s perspective, it was beautiful. He was one with the universe, seeing himself in the ultimate third-person perspective. Finally, he saw how it could be different if he didn’t let his OCD control him. And several months out, all the symptoms disappeared.
Ben’s story is one of many told in this series, which gives hope that help is right around the corner for the millions who suffer —often in silence— with debilitating mental disorders. But Michael Pollan’s work is showcasing the success stories. Often, even in the most successful trials, psychedelic-assisted therapy only helps up to a third of people enter remission. More frequently, patients are helped —sometimes substantially— but they still suffer with their illnesses and some people aren’t helped at all.

The second episode of the series immerses the viewer in a fascinating journey through the history of life on our planet, focusing on the evolution and adaptation of life in the seas. It begins billions of years ago, when the Earth was an inhospitable place and life was impossible on the surface due to a hostile environment. The documentary highlights how, beneath the waves, life began to flourish, protected from storms and other elements of nature. It addresses the development of photosynthesis by plankton and how this led to a significant change in the Earth's atmosphere, allowing the emergence of animal life.
This visually stunning narrative chronicles the evolution of various forms of marine life, from the earliest complex life forms to the appearance of the first fish and cephalopods. The documentary shows how marine life has influenced terrestrial life, emphasizing the impact of the 'greening' of planet Earth.
