Gavin Larkin was the ultimate alpha male: a highly successful advertising executive with friends in high places. But there was a problem with his seemingly perfect life. He was, as he says himself, 'a bit of a prick' and he was deeply unhappy. Gavin decided to change, and in 2009, he used his marketing nous and his high-profile contacts to create R U OK? Day, a national day of action to prevent suicide. But not long after the launch, the super-fit, indomitable Gavin was anything but okay. He died of cancer just after marking R U OK?’s third successful campaign. R U OK? Day has become one of the nation’s most embraced days of action. Six years after we first aired the story of Gavin Larkin, we return to his family to see how Gavin’s extraordinary legacy has helped sustain them through their grief.
