Filmmaker Annie Goldson and film subject Rob Hamill in person at all three screenings!

In 1978, Kerry Hamill and two friends disappeared without a trace while sailing from Australia to Southeast Asia. Rob discovers that a Khmer Rouge cell attacked the boat. One sailor, Canadian Stuart Glass, was shot immediately, but Kerry and Englishman John Dewhirst were taken to the notorious S-21 Prison in Phnom Penh, held for several months, tortured and killed. Thirty years later, Kerry's youngest brother Rob has a rare chance to take the stand as a witness at the Cambodia War Crimes Tribunal and face Comrade Duch, the man who gave the final orders for Kerry and thousands of others to be tortured and killed. As Rob retraces his brother’s final days, he meets survivors who tell the story of the S-21 prison and of what countless families across Cambodia experienced at the hands of the Khmer Rouge. In this spirit, Brother Number One grapples with the trauma that grips all Cambodia: the struggle to forgive in the face of immeasurable anger.

Human Rights Watch has examined the many problems besetting the Cambodian special court, established to try Khmer Rouge mass crimes. The court has been subject to frequent politically motivated interference from Prime Minister Hun Sen and his ruling party. Only one of four scheduled cases, that of Duch, has concluded. After the two investigating judges indicated that two of the cases, involving five defendants, would be dropped, Human Rights Watch called for their resignations. The German judge resigned one week later.
