Documentary filmmaker David Osit revisits one of the cultural phenomena of the early 2000s, Dateline's investigative TV series To Catch A Predator, which lured sex offenders to a film set and arrested them on camera. Host Chris Hansen was vaunted as a crusader for justice and morality and the candid camera format spawned various imitators hoping to mimic the ratings-grabbing success of the original. This feature-length film asks uncomfortable questions about why America has an obsession with watching people at their lowest. Director Osit turns the camera on himself, academics, law enforcement, journalists and actors to gain a clearer understanding of human behaviour and the TV show's complicated legacy
