^ [b]The girl next door [/b] Paige Collins and her husband Leo come out of a movie theater. On their way home, at a stop sign, Paige unbuckles her seatbelt to lean over and kiss Leo. At that very moment, a truck rams their car from behind and Paige crashes out through the windshield. Both of them are rushed to the emergency room, and as Leo, in a voice-over talks about how "moments of impact help in finding who we are" the movie cuts to how Paige and Leo first met. The scenes of how they courted, proposed and married are interwoven with the present.
