Brian Cox looks at our attempts to answer one of the most profound questions we can ask – are we alone in the universe? With scientists sending space probes to the furthest reaches of our solar system and beyond, the scientific search for alien life has begun. Inspired by a childhood love of science fiction, Brian still hopes to hear from ET. In this film, he explains why this search deserves to be taken seriously, and he explores the chances of it happening.

Jeremy Clarkson decides to become a naturalist. 'In just 30 years, insect numbers have dropped by 25% and they're still falling. Without insects, all life on Earth ends. Everywhere where insects like to live is disappearing and I've decided to do something about that. My plan is to make my hedgerows, my valleys, my woods, and my streams more attractive to creepy crawlies. In essence, I am going to leave chunks of the farm completely alone. I'm going to put Mother Nature in the driving seat. It's a process called wilding.'

As Covid-19 puts Britain on lockdown, Jeremy Clarkson suddenly finds that his biggest worries aren’t all related to the upcoming lambing season. 'If you're involved in food production, you are key worker. We're gonna save the nation!... I've smoked a million cigarettes and I've had pneumonia. If I get it , there's not a lot of hope... Am I panic buying? I bought five tins of sardines the other day'.

Jeremy Clarkson discovers why British farmers are always complaining about the weather. It’s mostly because it never does what they want it to do.

As the drought drags on with the sun continuing to blaze down from a cloudless sky and harvest time gets closer, Jeremy Clarkson and his motley crew have a fearsome list of jobs to complete.

After months of hard work Clarkson's farm arrives at a make or break moment; harvest time. 'It's always stunning on the farm, actually. Whatever the day, there's always something that's absolutely beautiful. The thing is, the show's now over, which is sad. But thank you very much for being so patient with me.'
