This episode looks at a group of black survivalists. British Buzzfeed correspondent Bim Adewunmi looks at an unusual group of doomsday preppers who don't fit the normal stereotype for that group. She interviews people of color who train themselves to prepare for disaster.

The story of Tilikum, a captive killer whale that has taken the lives of several people , including a top killer whale trainer, underscores the consequences of keeping these powerful animals in captivity, the problems within the sea-park industry, the man's relationship to nature, and how little has been learned about these highly intelligent and sentient mammals.
Tilikum was captured in the northern Atlantic Ocean in 1983 and taken to Sealand of the Pacific, a now-shuttered park near Victoria, British Columbia. Former Sealand trainers interviewed in 'Blackfish' say the park’s female killer whales would aggressively gang up on Tilikum, particularly when they were confined in a 20-foot-by- 30-foot pool overnight.

Garrett McNamara recovers from the injuries he sustained at Mavericks and begins training to return to Nazaré for another season. While surfing at Indonesia's G-Land site, Garrett suffers more injuries that threaten to take him off the waves permanently. Meanwhile, a friend of Garretts catches an 80-foot wave at Nazaré, taking the world record from McNamara. McNamara resolves to continue his hunt for a 100-foot wave.

As dozens of top surfers from across the world arrive in Nazaré to train and prepare for a major big-wave competition, Garret McNamara continues to struggle with his physical injuries and mental preparedness. He knows he is not ready to surf in the competition but seeing the other surfers makes him consider competing anyway. Garrett also has misgivings about the state of safety plans at the competition, and tries to convince the organizers to beef up their plans.

As training begins, the crew members process the physical, mental and technical demands being placed on them. The group is going to be in some intentionally uncomfortable situations and, to see how they do as a team. A climb of Mt. Rainier puts them to the test.

Frontline and service workers have borne the health consequences of the pandemic, increasing racial and economic disparities. Certain robotic and AI applications are accelerating as the value of human workers is further questioned. Determining the likely areas of job growth and training needs is difficult. Post-secondary education has become more virtual and its costs, more controversial. How can we predict job growth, training needs and the role of education in order to prepare for the work of the future?
