Some of Britain's worst learner drivers are paired with leading instructors to see if they can finally pass their test. Keeley from Essex has failed nine times over 21 years, and now the 40-year-old is hoping to get her licence with the help of former policeman Simon. However, she's quickly overwhelmed by the chaos of London's roads as she encounters narrow lanes, hectic roundabouts and heavy traffic. Meanwhile, super-instructor Ursula tutors retired teacher Malcolm, 65, who struggles to avoid steering into parked cars.
