The show is based on confrontations in which guests attempt to resolve issues with others that are significant in their lives, with such issues often related to family relationships, romantic relationships, sex, drugs and alcohol, among other issues.[5][6] Alongside Kyle, the programme additionally featured psychotherapist Graham Stanier,[3] who assisted the guests both during and after the show's broadcast, along with the use of a polygraph test ("lie detector") to determine the veracity of guests' claims, despite contrasting scientific research against the use of such a device.
