"Come on, nothing bad ever happens in Hawaii, right?"
A Perfect Getaway is about Cliff and Cydney. Cliff and Cydney are newlyweds who have decided to spend their vacation in Hawaii. Then, they find out when they get to a second island that a pair of serial killers— a man and a woman— are on the loose on the islands. They then run into Kale and Cleo, a pair of suspicious hitch-hikers and Nick and Gina, an ex-American Jedi and his girlfriend. All three couples wonder if the other two couples are the killers, all while wandering farther and farther from society and deeper into the jungle...
This film provides examples of:
Bad Ass: Nick. The things he's done are so awesome that Cliff doesn't believe they're even true. They are.
Better than a Bare Bulb: The writers basically punch through the surface of the movie to have two characters, neither of whom have any background in screenwriting, talk as though they're on a writer's retreat, trying to come up with a movie.
Becoming the Mask One of Rocky's rules of deception. There is even a scene showing how both Rocky and Cydney practice being the people whose identity they've stole, including mannerisms, accent, and background information on the victims family and friends.
Boom, Headshot: Cliff shoots Nick in the back of the head. Unusually for this trope though, Nick survives (due to the metal plate in his head).
Then at the end, Cliff gets taken out by a helicopter sniper this way.
Cerebus Syndrome: This movie starts out suspenseful, but also very funny. About halfway through, it gets really fucking disturbing.
Chekhov's Gun: The CB radios in the Kayak. It's fired in one of the best jump scares in recent years.
Also, early on, Nick boasts about having a titanium plate put in his skull due to a head injury. It later on proves instrumental in saving his life from getting shot in the head.
Crazy-Prepared: Both Nick and Rocky fit the trope. Nick when it comes to spotting and dealing with danger which he calls "Situational Awareness". And Rocky when it comes to killing, stealing identities, and covering his tracks. The plot twist flashback shows him obsessed with watching forensic crime shows.
Deadly Road Trip: Yep, alone in the wilderness with a couple of potential killers.
Decoy Protagonist: Rocky and Cyndey are actually the villains of the film, the plot twist flashback fills in a lot of background information and shows that Nick and Gina are the true protagonist of the film.
Driven by Envy: This gets Cyndey to turn on Rocky in the end, because she longed for a true loving relationship like Nick and Gina, but saw herself stuck with a sociopath who is incapable of such feelings.
Double Meaning Title: The Hawaiian hiking trail is a "perfect getaway" because it's a good vacation. It's also a good place to hide if you had just, say, killed a bunch of people and were trying to escape. Get it?
Gorn: The gore was fairly limited to a handful of shots in the last few minutes.
Heel-Face Turn: Cyndey has a change of heart after she sees how much Nick and Gina really do love each other, in contrast to the screwed up relationship she has with Rocky.
I Can Change My Beloved: It's implied during the flashback Plot Twist that Cydney believes she can get Rocky to truly fall in love with her with no success. She finally gives up on him during the climax.
The Reveal: Cliff and Cydney were a couple on the other island. He was a screenwriter, she was his wife. They told some dude named Rocky and his girlfriend all about their lives. Rocky and his girlfriend killed them, stole their identities and are the protagonists.
Too Dumb to Live: Fortunately, it's only a group of Spear Carrier kayaking dudes. Just remember, when you insist that your kayaks are more important than a hysterical woman screaming about a murderer on her tail, you deserve to die. You could've just moved the conversation down to the beach, couldn't you?
Too Good To Be True: Gina ask Cydney about her life. Cydney tells Gina how perfect her life is and how she plans to have lots of children with Cliff. Gina responds by telling her a story about a preacher who claimed to be holier than thou, only to get caught cheating on his wife with another man. She makes the point that people whom pretend to be perfect are liars. This gets Cydney to open up about how she really met Cliff, who is really Rocky.
Trailers Always Spoil: It's called A Perfect Getaway. In the trailer, they specify that the killers are a man and a woman. If you haven't put it together before you're in your seat, you must be a saint.
Twist Ending: Well, actually, it happens about halfway through the movie, but same difference, right?
Villain Protagonist: For some value of villain with Cliff and Cydney and some value of protagonist with Nick and Gina.
