The Imposter tells such a strange story! It's a documentary about a boy in Texas who goes missing, and is found nearly four years later in Spain. But it's not him. At all. Even though the boy's family accepts him and lets them in to their lives as if he were their missing son.
The Imposter is about a European guy who has a compulsion to impersonate abused and missing teenagers. He was 23 when he convinced authorities he was the missing 16 year old from Texas. Even though he has brown eyes and the missing boy has blue. There are many strange things going on, and it is creepy how the family seemed to accept him without question.
