Quinto sets out to discover whether aliens exist and what evidence we have to prove it. He meets with several who say they have encountered extra-terrestrial life–a man who has been abducted by aliens several times since childhood; a man who claims to have extracted an alien implant; and a woman who shows Zachary what it feels like to be abducted into a spacecraft. Zachary also meets with the world's leading scientists at SETI in Green Banks, West Virginia. There, utilizing the world's largest telescope, they show him the methods they employ to communicate with potential other-worldly visitors and what this research has taught them about a mysterious radio signal they picked up 3 billion light years away.
Marc-André Leclerc climbs alone, far from the limelight. On remote alpine faces, the free-spirited 23-year-old Canadian makes some of the boldest solo ascents in history. Yet, he draws scant attention. With no cameras, no rope, and no margin for error, Leclerc's approach is the essence of solo adventure. Nomadic and publicity shy, he doesn't own a phone or car, and is reluctant to let a film crew in on his pure vision of climbing. Filmmaker Peter Mortimer sets out to make a film about Leclerc but struggles to keep up with his elusive subject. Then, Leclerc embarks on a historic adventure in Patagonia that will redefine what is possible in solo climbing.

The Arctic is the harshest environment on Earth: little food grows, it's dark for months on end, and temperatures stay well below freezing for much of the year.

In springtime, Amos and Karl-Frederik set out across the sea ice with their dogs to catch a real-life sea monster: a Greenland shark! Inuit mussel-gatherers venture underneath the sea ice at low tide for a perilous race against time as they gather their food.

Who'll get the tastiest snack?
