Corals build themselves homes of limestone in the warm, clear, shallow seas of the tropics. Their reefs occupy less than one tenth of one per cent of the ocean floor, yet they are home to a quarter of all known marine species. The broad-club cuttlefish has found its place by using a hypnotic display that apparently mesmerizes its prey, causing it to let down its defences. On the Great Barrier Reef a remarkable grouper uses sign language, dubbed the headstand signal, to reach out to an entirely different creature, a reef octopus, to flush small fish out of their hiding holes and into the groupers waiting mouth.

The second part of the series describes how Honda withdrew from Formula 1 and how Ross Brawn and Nick Fry took control to form Brawn GP. It explains the team's financial struggles, their ingenious interpretation of the rules to develop an innovative double diffuser, and the subsequent controversies and legal battles with other teams over the legality of this innovation. The rivalry between Jenson Button, the team's lead driver, and his teammate Rubens Barrichello is emphasized. The climax of the film is Button's victory in Monaco, highlighting both the driver's triumph and the team's success under extreme pressure. As the season progresses, other teams begin to catch up to Brawn GP, increasing the pressure on Button to maintain his championship lead.
The documentary concludes with Brawn GP, pressured by financial needs, signing an agreement with Ecclestone, apparently betraying FOTA (Formula One Teams Association) and creating significant internal conflict. This twist highlights the complex power dynamics and ethical challenges within the world of F1.

In part two, Professor Al-Khalili looks at the 19th century chemists who struggled to impose an order on the apparently random world of the elements. From working out how many there were to discovering their unique relationships with each other, the early scientists' bid to decode the hidden order of the elements was driven by false starts and bitter disputes. But ultimately the quest would lead to one of chemistry's most beautiful intellectual creations - the periodic table.

Did China hide crucial information about Covid-19 from the world? What began with a handful of mystery pneumonia cases in Wuhan late last year has now left more than half a million dead worldwide. Beijing says it has been open and transparent throughout, but former BBC China Editor Carrie Gracie investigates how it delayed reporting the initial outbreak and evidence that Covid-19 could be spread by people. It also silenced doctors who tried to speak out.
The film also hears from one high-level insider who believes the animal market at the centre of the Wuhan outbreak should have been treated as a 'crime scene' and from experts who warn that this crisis may be a 'dress rehearsal' for an even more deadly pandemic in the future.
