The Imposter (2012)

In 1997, French serial imposter Frédéric Bourdin claimed to be Nicholas Barclay, a thirteen year old boy who had disappeared in Texas three years previous. Bourdin somehow convinced Nicholas’s family that he was their lost relative and lived with them for almost five months before his ruse was uncovered. Even through interviews with Bourdin and the Barclays, it remains unclear why the family fell for the hoax and the documentary throws out some potentially nefarious reasons. In the end, there are no answers and the disappearance of Nicholas Barclay remains unresolved.
