(Click CC for subtitles) Descending to remarkable depths below the sea on one single breath, Alessia Zecchini enters what she describes as the last quiet place on Earth. The Italian champion is determined to set a new world record in freediving, a dangerous extreme sport in which competitors attempt to reach the greatest depth without the use of scuba gear. Freedivers are often subject to blackouts upon ascent, necessitating the help of safety divers like Stephen Keenan, a free-spirited Irish adventurer who fell in love with the sport in Dahab, Egypt.
Having formed a special bond on the freediving circuit, Alessia and Stephen train together to make an attempt on Dahab’s legendary Blue Hole and its challenging 85-foot-long tunnel 184 feet below the Red Sea, their fates inextricably bound together.

In his second year in the team, Haas driver Mick Schumacher faces a lot of pressure, which is not helped by a lot of expectations from being a Formula Two World Champion and being the son of a seven-time World Champion. The paddock travels to the Jeddah Corniche Circuit for the second running of the Saudi Arabian Grand Prix; as qualification for the race begins, Mick's run grinds to a halt when he suffers a big crash, ruling him out of the race due to the damage sustained to his car. Schumacher continues to struggle after Saudi; in Miami, Schumacher, in ninth place, collides with Sebastian Vettel, taking both drivers out of the race; he starts his Monaco run at the back of the field, only to lose it coming into the swimming pool section and splitting his car in half in the ensuing crash.
By the time the paddock has traveled to Baku, Magnussen has led the championship for the Haas team with 15 points against Schumacher's 0, and faces a lot of pressure over his future in the team. Schumacher starts the race in last place, while Magnussen rises up the field. However, Magnussen's race is stopped due to an engine issue, leaving Haas' chance for points in the hands of a slow-running Schumacher. Indeed, Schumacher is running very slowly to the point he is lapped by the leading Verstappen. Away from the track, Schumacher trains with his personal trainer, convinced he can still score points.
At Silverstone, Schumacher starts at the back of the grid, but the session is red-flagged due to a big crash for Zhou Guanyu, which the Haas drivers manage to avoid. Schumacher and Magnussen are due to start 16th and 14th, respectively. Schumacher pushes through the field - and with an overtake on Ricciardo, a DRS-assisted overtake on Vettel - and ultimately Verstappen, he ultimately manages to finish eighth - his first points in Formula One, sending the Haas pit wall into a celebration; Vettel and Verstappen also congratulate Schumacher for his efforts during the race. However, despite his efforts in the race, Mick's seat in the Haas team remains open.

Clarkson's herd of cows begins to settle in on the farm, but things immediately begin to go awry. The cows aren't keen on the idea of a fence and quickly escape, and when Clarkson attempts to wean the calves, they too break out and cause chaos. In addition, the new roosters brought in to help fertilize the soil also prove to be difficult to handle.

Everyone's still reeling from the council's decision and its implications: the money Jeremy's spent on cows for the restaurant, the locals who won't find work there now and the farmers' co-operative that's now defunct. Charlie sets out to find a legal team to help Jeremy appeal the decision, as Jeremy and Kaleb get to work on tagging the new calves and attempting to navigate a government helpline where you're supposed to register them.
There are other useful distractions from the council in the shape of Diddly Squat's Hedge Laying Competition and a mouse that brings the whole farm to a standstill. The legal team that Charlie has assembled pay a visit. They outline their strategy for the appeal, but also the costs that come with it.

The series follows the tragedy that occurred when terrorists attacked at the annual Boston Marathon on April 15, 2013. They carried out the attack by placing two homemade pressure cooker bombs which detonated near the finish line of the race 14 seconds and 210 yards (190 m) apart. That resulted in three fatalities and hundreds injured, including 17 who lost limbs. With the help of archive footage, interviews with investigators, witnesses, survivors, and occasional reenactments, it offers details about the FBI investigation into what was quickly deemed a domestic terrorist attack.
In the first episode, hours after the blasts, investigators pore over evidence. One photo and a few seconds of footage lead to a breakthrough - and an agonizing choice.

In the final episode, we hear how employees on the 17th floor were rewarded, and we see Madoff's $65 billion Ponzi scheme quickly collapses as investors begin to withdraw their money during the 2008 Financial Crisis. We see how Madoff's sons attempt to stop their father from writing bonus cheques for long-time investors, faithful employees, and extended family to help cushion the blow. Madoff confesses to the Ponzi scheme, and the FBI arrests him.
After pleading guilty, Madoff is sentenced to 150 years in prison. Two years after learning of the Ponzi scheme, his eldest son Mark is found hanging from a pipe, dead of an apparent suicide. His other son dies of lymphoma six years later.
