Overview: The harrowing story of one man's efforts to stop children being sexually exploited in Costa Rica. Bruce Harris infiltrated a paedophile porn ring and went undercover as a customer in a child brothel to get evidence that has finally led to prosecutions - but also death threats. The film reveals the wider world picture of a growing trade that needs individuals, international governments and the tourist industry to act together to make a difference.
