What would you do if you took your family for a fun day at Universal Studios, watched your husband and son go on a ride and when they return... they are completely different people?

For Jack Connors it's a nightmare when he tries to convince park security, police, and then hospital staff that the two people claiming to be his loved ones are impostors. Worse... he has no proof. They are far from home and the only photo in his wallet is that of the man and child from the ride.

Something sinister is afoot but Jack isn't quite sure what... or why his whole world has just gone haywire.
