Oscar Pistorius, the South African Olympic sprinter, shot his girlfriend Reeva Steenkamp through a locked bathroom door in the early hours of a February morning, and this film has two South African lawyers pick apart the case built around that shooting. Their main tool is a purpose-built replica of Pistorius' bedroom and bathroom, used to walk through the trajectory of the bullets and test whether his account, that he mistook Steenkamp for an intruder, holds up against the physical layout of the room. The lawyers weigh the prosecution's reliance on circumstantial evidence against the defense's use of Pistorius' disability and anxiety history, and ask whether either side's strategy amounted to a fair fight. The film sets the case against South Africa's high rate of gun ownership and its record on domestic violence, and tracks how media coverage and public opinion pressed in on a trial already complicated by Pistorius' celebrity. The central dispute stays practical throughout: what the physical evidence in that bathroom can and cannot prove.
