Michael Stevens investigates how and why different interrogation techniques work, and the ethics behind them. The first experiment is one on Michael himself. Midazolam, commonly know as 'truth serum', is injected into his bloodstream and he tests out how effective it is. Secondly, after talking about the 'good cop - bad cop' power dynamic he sets up an experiment where he tries to get a confession out of unknowing participants using this technique. In the third and last segment they try to beat a state of the art lie detector.
