'Cancun'-bound Taylor Lautner has a backup plan: personal trainer

The word is out that Taylor Lautner is planning a trip to Cancun, Mexico.

But it's not a vacation.

Summit just picked up "Cancun," an action suspense flick as a starring vehicle for Lautner, which may be produced by him and his dad, Dan Lautner.

The story is about nerdy college kid who travels with a girl to Cancun on a break. 

While there, the girl and her friends are taken hostage by a drug cartel of vampires and he is forced to save them by turning into a werewolf.
