The series is a thorough examination of the infamous UFO cult through the eyes of its former members and loved ones. What started in 1975 with the disappearance of 20 people from a small town in Oregon, ended in 1997 with the largest suicide on US soil and changed the face of modern new age religion forever.
In the first episode, Bonnie Nettles and Marshall Applewhite begin to recruit individuals interested in end-of-the-world Christianity, new age religion, and UFOs - but the disappearance of new members soon drives media attention and family concerns.

Of all the diseases that plague humankind, malaria has put up one of the longest, toughest fights. More than 200 million people fall ill and 600,000 die of it every year, making it among the world’s deadliest diseases. The vast majority of those fatalities are young children - an average of one child every minute. But medical science may now be at an exciting turning point.
Filmed with intimate access to key scientists on four continents, this documentary tells the inside story of the development of a new malaria vaccine that could change the very nature of the fight. It's hoped that the vaccine, dubbed R21/Matrix-M and developed by many of the same team behind the Oxford/AstraZeneca Covid-19 vaccine, will be the first to meet the World Health Organization’s target of 75 per cent efficacy.
