In 2003 Mark Henderson was one of eight backpackers taken hostage whilst trekking in the Colombian jungle. What had started as an innocent tourist adventure, ended up as 101 terrifying days of captivity and uncertainty about his future. Eleven months after his release Mark received an email from Antonio, one of his kidnappers, and one of the other hostages received a facebook friend request from Antonio's girlfriend, another of their captors. That email was the start of a five-year correspondence between hostage and kidnapper that eventually drew Mark back to the one part of the world he thought he'd never see again and face to face with the man who had once held the key to his freedom. My Kidnapper is an emotional journey into a kidnapping, told from all sides. This deeply personal, authored documentary follows Mark and three of his fellow hostages as they return to the Sierra Nevada mountains in northern Colombia, the place where they lived out their worst nightmares. As they ravel deeper into the jungle, they discover the truth behind what happened to them, come to understand how they all dealt with the ordeal and finally confront two of their kidnappers.
