The Imposter (2012)

In 1994, a 13-year-old boy from a family in San Antonio, Texas, disappeared on his way home. His name was Nicholas Barkley. The incident was not reported by the news media, and three and a half years later, his family thought he was dead, but a group of tourists found a delirious boy claiming to be missing Nick in a small town in southern Spain. Nick's mother was in poor health and his sister Carly came to Spain to take him home in Texas. However, is the person in front of him really Nick?
