In this week's programme, Richard Hammond is dropped into the remote, frozen wastes of Canada to test a watch with a built-in emergency beacon. The distress signal is sent directly to Jeremy Clarkson and James May, who get their hands on two machines and set off on an epic adventure to find their colleague. Plus, Jeremy puts the new 471bhp Lexus RC F coupe thought its paces, while The Fall and The X-Files star Gillian Anderson takes to the track in the Reasonably Priced Car.

This episode of Top Gear features two films that were shot for the previous series. In the first film, Jeremy, Richard and James immerse themselves in the lifestyle of the traditional classic car enthusiast.Armed with affordable classics including a Fiat 124 Spyder, a Peugeot 304 Cabriolet and an MGB GT, the trio set off on an adventure that includes brown beer, breakdowns and a hair-raising classic car show.

In the second film, Clarkson, Hammond and May try to become lifestyle leisure enthusiasts with the help of some incredibly cheap lifestyle leisure vehicles. Restricted to a maximum budget of £250, the trio buy three massive mileage SUVs - a Vauxhall Frontera, a Jeep Cherokee and a Mitsubishi Shogun - and then embark on a series of action-packed challenges that include battling with the Stig's 'Leisure Activity Cousin' and a race with terrifying consequences for the loser.
