On 4 December 2008, just a few months before the new season was due to start, the Honda Racing F1 team, which Jenson Button had been driving for since 2006, pulled the plug on their involvement in Formula One. The media at the time reported that it was likely that the factory would be forced to shut and it was unlikely that Jenson would be able to secure a drive at a top team at this late stage. Yet incredibly, in October 2009, Jenson Button was crowned World Champion and the new team that had risen from the ashes of the Honda Racing F1 team - Brawn GP - secured the constructors' championship in their first season, a feat never before achieved. If this were a movie script you wouldn't believe it possible, so how did it happen? A CHAMPIONSHIP YEAR tells Jenson's incredible story of the 2009 season.
