The movie has two endings; one for the theatrical release, and an alternate version included in the movie's DVD. In the first, after a brief dialogue with Telly, the man creates an illusion of Sam which Telly chases through the hangar, and then confronts her again. He reveals that the purpose of the experiment is not to investigate the children, but rather the bond that exists between a parent and child, and that he believes it can be broken. He admits, however, that the experiment has so far produced no positive results with regards to Telly, and that it will fail soon if she doesn't forget, and he will be responsible for that failure. However, despite him revealing himself as an alien and almost succeeding by stealing the memory of Sam's birth, Telly can still remember her son, and he is whisked away by an unseen force, presumably to face the consequences of failure. Reality is restored to normal, and Telly is the only one who can remember the events that transpired. The alternate version is very similar, except that Telly is faced with a facsimile of Sam's room. She tries to force her way in, but cannot reach Sam. The alien scientist tries to convince her to forget Sam, but fails. He then accepts that the experiment has failed, and explains that she will be the only one who remembers what transpired there. Reality is again restored to normal.
(Jan 2009) The network cable versions have changed the plot by removing all mention of the children being involved in a plane crash. Instead, the "died" in a bus crash. The word "bus" is dubbed in throughout. Newspaper articles are edited to reflect this. Also, the company "Quest Airline" is edited in dialog and on screen as simply "Quest".
