In Scotland, she reveals the strategy behind Britain’s nuclear deterrent, and speaks to campaigners in Suffolk fighting against US weapons they fear will be based on UK soil. Jane also discovers how many of the global agreements and safeguards that have constrained the spread of nuclear weapons since the 1970s are breaking down.
This is a story told by the scientists, investigators and diplomats who set the clock and have fought to ensure that the ultimate deterrent has not been used in over 70 years.

Offering unprecedented access, Season 5 will once again take fans behind the scenes, to witness first-hand how the drivers and teams prepare to battle it out for victory in one of the sport’s most dramatic seasons to date.
The first episode begins with a recap of the closing laps of the 2021 Abu Dhabi Grand Prix controversy. After showing how important the relationship is between Guenther Steiner and Mattia Binotto for their respective teams, the 2022 Formula 1 season opens with pre-season testing at the Circuit de Barcelona-Catalunya. The teams and drivers all prepare their cars for the upcoming races. This year also marks the largest changes to the cars in many years.
Controversy arises when Haas F1 Team drops its major sponsor Uralkali along with its sponsored driver Nikita Mazepin due to the Russian invasion of Ukraine. Haas brings back Kevin Magnussen after he was let go from the team back in 2020. Current World Champion Max Verstappen finally makes an appearance on the show after having declined to appear in previous seasons. In the early races many teams, especially the Mercedes-AMG Petronas F1 Team, have to deal with issues of porpoising, a potential problem related to Ground Effect, which returned after having been banned in 1982. The first race, the 2022 Bahrain Grand Prix, is shown with both of the Red Bull cars losing power, Scuderia Ferrari achieving their first win in 910 days with their drivers Charles Leclerc and Carlos Sainz Jr. taking first and second place respectively and Kevin Magnussen achieving fifth place on his first outing back at Haas.

Under the management of new team principal Otmar Szafnauer, Alpine F1 Team goes into 2022 retaining their drivers Fernando Alonso, a veteran of Team Enstone and two-time Champion, and Esteban Ocon, the driver who took Alpine to their first victory since 2014, with a new reserve driver in Australian driver and 2021 Formula Two champion Oscar Piastri. Alpine scores consistent points scores in Miami, Baku, and Austria.
By the French round - the home race of Alpine - McLaren and Alpine are tied for sixth in the Constructors' Championship. Early into the race, Alonso edges past Lando Norris for fourth, with Ocon behind him. However, Ocon inadvertantly takes Yuki Tsunoda out of the race, giving him a five-second penalty. Pitting soon after drops him down out of the points, with Alonso now sixth and a second behind Norris. Alonso holds the McLarens up to buy enough time for Ocon to pass them. Alonso finishes sixth and Ocon eighth in their home race.
Before Hungary, it is revealed that four-time Champion Sebastian Vettel will retire from Formula One, sending the paddock and media into a frenzy with the prospect of a ‘silly season’ on the horizon for Aston Martin; Szafnauer is adamant that Alonso is staying with Alpine for 2023. Hungary is the make-or-break round for Alpine - both drivers need to score higher points than McLaren to achieve fourth in the Constructors' Championship. Ricciardo and Lance Stroll both overtake the Alpines, but Ricciardo punts Stroll off the track, giving him a five-second penalty. Alonso and Ocon barely hold on to the points, and Ricciardo finishes fifteenth after his penalty, allowing Alpine to secure fourth place. The team and their title sponsors BWT celebrate at a sponsor dinner. The next day, Alonso reveals he had received a call from Aston Martin team owner Lawrence Stroll to replace the outgoing Vettel, moving him out of Team Enstone. Left with no other option, Alpine announce Piastri for the 2023 season, and McLaren are looking to replace Ricciardo with Piastri, who they have had eyes on. To make matters worse for Alpine, Piastri announces on Twitter that he will not be driving for the team, considering he had not signed such a contract with them.

With Pierre Gasly announcing his departure from Alpha Tauri, Yuki Tsunoda has lost both a teammate and a friend. As Gasly leaves the Red Bull family for the first time in his career, more is expected of the young Tsunoda at Alpha Tauri, who is now being asked to prove that he is ready to take charge.

A team of Ukrainian journalists from The Associated Press trapped in the besieged city of Mariupol struggle to continue their work documenting atrocities of the Russian invasion. As the only international reporters who remain in the city, they capture what later become defining images of the war: dying children, mass graves, the bombing of a maternity hospital, and more.
Drawing on director Mstyslav Chernov's daily news dispatches and personal footage of his own country at war, the film is a vivid, harrowing account of civilians caught in the siege, as well as a window into what it's like to report from a conflict zone, and the impact of such journalism around the globe.

In the first episode, Sir David Attenborough reveals the unexpected wildlife riches of the British Isles, showcasing the dramatic and spectacular habitats that rival any across the globe. This journey uncovers the diversity of life in the UK's unique landscapes, from the intricate world of bumblebees to the swift lives of kingfishers. The episode captures extraordinary scenes of nature, including killer whales preying on seals, golden eagles in the Scottish mountains, the cunning tactics of woodland plants, and the perilous life of puffins evading gulls. It highlights Britain's geological diversity as a cornerstone of its natural wealth, contributing to an array of habitats and supporting a wide range of life.
Britain's importance extends to being a haven for migratory birds, with our seas feeding 65% of the world's gannets and supporting the largest colony of northern gannets on Scotland's Bass Rock. The west coast of Scotland offers sanctuary to barnacle geese due to its abundant food and mild climate, though they remain vigilant against hunting sea eagles. Despite these natural treasures, Britain faces challenges as one of the most nature-depleted countries globally. Sir David Attenborough emphasizes the need to conserve and restore these wild isles for the enjoyment and benefit of future generations.
