This movie has Steve Zahn and Milla Jovovich as a newly married couple on their honeymoon in Hawaii. They are hiking a remote trail and run into two other couples along the way. There are killers (a man and woman) on the loose on the island and the movie is basically figuring out which couple is the killer couple.

This movie was just stupid. You will know who the killers are a mile away (though the "reveal" just takes it to even stupider new places and makes very little sense). I give it a 'D' for "don't bother!"
