13-year-old Nicholas Barclay disappeared from his neighborhood in San Antonio, Texas, on June 13th, 1994. For three years, his family searched for their missing Nicky - until they got the shocking call that he was alive in Spain. For almost 5 months, the family believed the person staying in their home was their long lost son. But another shock came when it was revealed that this person was not Nicholas - it was 23-year-old French serial imposter Frédéric Bourdin. Frédéric admitted his lie - but he believes the family knows what really happened to Nicholas, who is still missing today.
