Nils Melzer, the UN Special Rapporteur on Torture, joined director Stephen Bennett and guests for a discussion after this special screening.

Through extensive interviews, the film uncovers how hundreds of secret experiments conducted since the 1950s influenced interrogation practices in the US and UK. At the centre of the collusion was Ewen Cameron, whose Canadian practice received millions of dollars to conduct experiments on sensory deprivation and overload on his vulnerable patients.
