Ep 1. Icelandic volcano

In the first episode of season 15 of Top Gear, the trio of presenters - Jeremy Clarkson, Richard Hammond, and James May - take on an epic road trip through the stunning and treacherous terrain of Iceland.

Their journey begins with a cheeky prank on Hammond, who is tricked into thinking that they are going on a luxury spa holiday instead of a rugged off-road adventure. But soon enough, they are driving through a punishing landscape of volcanic craters, lava fields, and ice sheets.

Along the way, the presenters test a trio of high-performance sports cars - the Porsche 911 Turbo S, the Lamborghini Gallardo LP560-4 Spyder, and the Aston Martin V12 Vantage - to see how they fare in such extreme conditions. Clarkson, May, and Hammond put the cars through their paces, testing their speed, agility, and endurance on rough roads and in deep snowdrifts.

As they navigate their way through Iceland, the presenters also take the time to explore the country's unique culture and history. They visit a traditional Icelandic village, sample local cuisine such as fermented shark and whale, and learn about the ancient sagas that have shaped the country's identity.

However, their journey takes a dramatic turn when they encounter the aftermath of an actual volcanic eruption. Driving through a landscape littered with ash and debris, they witness the stark beauty and destructive power of the natural world.

Despite the challenges they face, the Top Gear trio perseveres, tackling hairpin turns, icy roads, and treacherous river crossings. Along the way, their camaraderie and humor keep the journey entertaining and engaging for viewers.

Overall, the first episode of Top Gear season 15 offers a thrilling and insightful look at one of the world's most awe-inspiring landscapes, as well as showcasing some of the world's most impressive sports cars in some of the harshest conditions imaginable.
