In the fourth episode, several women recall their harrowing experiences with one man's heinous attempts at virtual blackmail, aimed at obtaining sensitive sexual material.

A guide to plants that thrive in human-dominated environments, including trees that grow across canyons in India, which have developed into living bridges. The programme examines the origins of growing crops and the ongoing influence on the world of wild plants, as well as efforts to preserve species, from snipers firing pesticide bullets from helicopters to fend off invasive plants to plants being painstakingly pollinated using a paintbrush.

Plants that have developed to thrive in the desert, including cacti that grow in the shade of other trees and collect water in pleated trunks that expand and contract - but can also find themselves a host to other plants, like desert mistletoe. This programme also reveals how tobacco plants being eaten by caterpillars are able to summon the creatures' natural predators, and how tumbleweeds roll across the landscape, only unfurling and growing when they encounter rain.

Dive with David Attenborough into a world where a single life can last a thousand years. See things no eye has ever seen, and discover the dramatic, beautiful plant life of Earth. In the first episode, Sir David Attenborough shows how more kinds of plants are crammed together in the tropical rainforests than anywhere else on Earth. The result is astonishing beauty and intense competition - a plant battleground.
New filming techniques allow us to enter the plants’ world and see it from their perspective and on their timescale. From fast-growing trees to flowers that mimic dead animals, this is a journey into a magical world that operates on a different timescale to our own.

The First Amendment and the very idea of free speech are under attack in America today. A growing number of Americans don't believe you have the right to speak your mind if what you have to say might offend someone, somewhere. They advocate for 'safe spaces' in which people won't be offended by ideas they may find troubling. But is that what America is about?
In No Safe Spaces, comedian and podcast king Adam Carolla and radio talk show host Dennis Prager travel the country, talking to experts and advocates on the left and right, tour college campuses, and examine their own upbringings to try to understand what is happening in America today and what free speech in this country should look (and sound) like.

They have the raw talent, but can they handle the pressure? Now Yuki Tsunoda and Esteban Ocon must sink or swim in the rough waters of Formula 1. Yuki Tsunoda had to move from Tokyo to Milton Keynes and F1 cars are proving a bit more difficult to wield than the F2 machine in which he won races. Esteban Ocon is part of the all-French attack (from Enstone) in the shape of Alpine, soaking up the pressure to win the Hungarian GP.
