a perfect getaway

this one is a hidden gem!  the story follows two couples who go on a vacation to a beautiful island getaway.  they are having a great time and spend the day hiking through the gorgeous trails of the island.  while on the trail they meet up with another couple who asks to join them.  as they continue on the hike things start to get weirder and weirder as the two friendly couples realize that this third couple may not be who they claim.  the locations are amazing and the tension amps up so well that you cant help but get drawn in and feel for these couples.  also, a very fun cast with steve zahn, milla jovovich, and chris hemsworth.
