Two Dutch lawyers, Michiel Pestman and Victor Koppe, travel to Cambodia in 2011 to defend Nuon Chea in an international tribunal. Nuon Chea, also known as Brother No. 2, was the second man after Pol Pot in the Khmer Rouge regime. He is being charged with mass murder and crimes against humanity. For four years, the documentary follows the lawyers in their attempt to give this man a fair trial, but the UN tribunal is beset by local interests and a government which consists partly of other former members of the Khmer Rouge who would really like all of the blame to rest solely on the defendant. What should've been the crowning achievement in the careers of the lawyers turns out very different.

Defending Brother No.2

When successful banker Thomas attends his father’s funeral, he meets his left-wing activist brother Arne again after many years. He makes an effort to get close to Arne and invites him to a prestigious conference on sustainable banking, but Arne uses the conference to make a political statement that has fatal consequences. Thomas finds himself fighting for his own career and for Arne’s life, but especially to regain his brother’s respect.
