Abduction (2011)

Abduction is a 2011 action thriller film directed by John Singleton and starring Taylor Lautner, Lily Collins, Sigourney Weaver, Maria Bello, Jason Isaacs, Michael Nyqvist, and Alfred Molina. The film is about a teenager who discovers that the father and mother he has been living with throughout his youth, are not his real parents -- when he sees his baby picture on a "Missing People" website. The film was released by Lionsgate on September 23, 2011.

Nathan Harper (Taylor Lautner) is an 18-year old who lives with his "parents", Kevin (Jason Isaacs) and Mara (Maria Bello). He has been having recurring nightmares throughout most of his youth, and was recommended by his school counselor to consult psychiatrist Dr. Geraldine "Geri" Bennett (Sigourney Weaver), to discover why.

During sociology class one morning, Nathan is partnered with his next-door neighbor and longtime friend Karen Murphy (Lily Collins) for a school assignment about missing children.

While doing the homework together, Karen finds a website that, through age-progression technology, shows what children would look like as they got older. Nathan discovers that a boy named Steven Price, aged approximately 3 years when photographed 15 years ago, would look exactly like him in the present day.

He goes to the basement, where his childhood items are kept and also finds the same shirt that 4-year-old Steven in the picture is wearing. With the confirmation of a particular stain on that shirt's sleeve, he suddenly realizes that he and Steven are the same person.
