For their honeymoon, newlyweds Cliff and Cydney travel to
Hawaii. After making a travel video in the car, they spend the night in a hotel before driving off in order to start hiking towards a remote beach. Whilst in the car, the two encounter another couple: kind-hearted Cleo who attempts to hitchhike with them and hot-headed Kale who takes her away from them. On the hike, they are befriended by tourist Nick and his girlfriend Gina. The two couples go forward on their journey together, but tensions begin to arise in the group when a double homicide of an unidentified couple is reported in Hawaii, with a man and woman being suspected as the killers. When the four arrive at a waterfall; Kale and Cleo are also there. Kale makes vague threats to Cydney, which seemingly worries Cliff. Nick, discovering that Cliff is a screenwriter, attempts to convince him to write a script about him; he was a soldier and had his skull crushed, but survived thanks to an operation where metal plates were put in his head. Cliff lets Nick continue on about this throughout the journey, despite having no interest in making a movie about him. After moving on, the four go deeper into the jungle and become wary of each other due to the reported murders. However, the tensions die down after they witness Kale and Cleo being arrested for the murders after some teeth were found in Kale's backpack. Arriving at their destination, Cliff convinces Nick to explore a marine cave with him while Cydney and Gina wait behind on the beach. After Gina looks through photos in a camera, she suddenly screams at Nick and Cliff. However they ignore her, so she begins to scale a cliff after them with Cydney in pursuit. Once alone with Cliff in the cave, Nick realizes that he has been tricked as Cliff draws a gun. It is revealed that the real Cliff and Cydney were the unidentified victims of the double homicide, murdered by their impostors. The impostor Cliff is Rocky, the high school boyfriend of the imposter of Cydney, and the two are meth addicts who have been committing the murders to assume the identities of their victims - getting the victims life stories by pretending to be scriptwriters. Gina, who saw the wedding photos with the real Cliff and Cydney on the camera, witnesses Rocky shoot Nick and attempts to escape. After fighting him off, but being stabbed and shot, Gina runs into the jungle. Rocky tells his girlfriend to mislead the police about the transpiring events while he chases after Gina. Gina finds some men but Rocky kills them all and seriously injures her before she manages to escape. Rocky's pursuit of her is stopped by the emergence of Nick, who survived the gunshot due to the previously mentioned metal plates. Nick gains the upper hand and holds Rocky at gunpoint, but a police helicopter contacted by Rocky's girlfriend arrives on the scene, warning Nick that he will be shot if he does not release Rocky. As Rocky tries to goad Nick into killing him, Gina gets Nick to back down. Realizing that she can stop Rocky, who is extremely abusive, and save two people who love each other, Rocky's girlfriend tells the police Rocky is the murderer, prompting them to shoot him when he tries to retrieve his gun. Travelling back on a helicopter, Nick finally proposes to Gina. She accepts, and they mutually agree not to go on a honeymoon. ==Cast==
