Peter sold tickets for seats on a moon landing. Marc sold holiday homes that he didn't own. Torsten impersonated a diplomat to organise a NATO security conference.Four pathological liars who lived for years as professional conmen are the subject of this engrossing documentary from director Alexander Adolph.The stories of brazenly swindling the unwary out of their savings make for absorbing listening. However, Adolph gradually moves beyond the conmen's bragging to tease out a fascinating profile of a conman's outlook on the world, providing insight into the ways they justify their actions to themselves. Also interviewed are some of the victims of the scams, offering a sobering reminder of the human wreckage these silver-tongued men have left in their wake.
