Gaby Roslin and Amir Khan present a program in which they apply the latest science to some of the worst sleepers. They include an extreme snorer, a man who suffers from night terrors, a woman who has restless leg syndrome, and a man with chronic insomnia for 20 years. The film also shows a sleep deprivation experiment to test for risky behaviour, pain resistance and emotional control. When the subjects reach the final hours of the challenge, the experiment begins to take its toll as the participants' emotions go into overdrive, with one threatening to quit altogether.
Fourth episode examines how plants either share environments harmoniously or compete for dominance within them. Attenborough highlights the 1987 hurricane and the devastation it caused. However, for some species, it was that opportunity for which they had lain dormant for many years. The space left by uprooted trees is soon filled by others who move relatively swiftly towards the light. The oak is one of the strongest and longest-lived, and other, lesser plants nearby must wait until the spring to flourish before the light above is extinguished by leaves. Tropical forests are green throughout the year, so brute force is needed for a successful climb to the top of the canopy: the rattan is an example that has the longest stem of any plant. As its name suggests, the strangler fig 'throttles' its host by growing around it and cutting off essential water and light. Some can take advantage of a fallen tree by setting down roots on the now horizontal trunk and getting nutriment from the surrounding moss and the fungi on the dead bark. The mountain ash (eucalyptus regnans) grows so tall, that regeneration becomes a considerable problem. It is easily flammable, so its solution is to shed its seeds during a forest fire and sacrifice itself. It therefore relies on the periodic near-destruction of its surroundings in order to survive. Attenborough observes that catastrophes such as fire and drought, while initially detrimental to wildlife, eventually allow for deserted habitats to be reborn.

Nintendo was like an impossibly huge wall. But if Mario was the undisputed king, an underdog was about to declare war. For Japanese game maker Sega, mainly known for its arcade cabinets, the battle was about winning the home console market. Sega's Genesis console and its speedy character, Sonic, hit the market. In the early '80s, sports video games existed, but they didn't really look real. And one visionary entrepreneur had already started tackling the challenge of taking sports from the stadium onto the screen. Electronic Arts kicks off a partnership with football legend John Madden.
