The Imposter(2012)

A 13-year-old boy disappears without a trace from San Antonio, Texas in 1994. Three and a half years later he is found alive, thousands of miles away in a village in southern Spain with a story of kidnapping and torture. His family is overjoyed to bring him home. But all is not quite as it seems. The boy bears many of the same distinguishing marks he always had, but why does he now have a strange accent? Why does he look so different? Any why doesn't the family seem to notice these glaring inconsistencies? It's only when an investigator starts asking questions that this strange tale takes an even stranger turn.
