What it conveys is rather elusive and the film later morphs into something that changes its perspective altogether. It’s difficult to describe in a review like this, but we’ll try. So be warned, if you intend to watch the movie, don’t read this review as there will be lots of spoilers!
Matthew McConaughey plays a fishing boat captain, Baker Dill, who lives in a remote island called Plymouth. He and his first mate, Duke (Djimon Honsou), takes out rich men into the ocean to catch fish for a good price. But he is not really keen on conducting good business as he is more obsessed with catching a large fish that he calls Justice, feeling like Captain Ahab to Moby Dick, but some folks say the fish is just a figment of his imagination.

Frank is powerful enough to get rid of them if ever they’d try to leave him. He is scheduled to arrive in the island the next day and Karen wants Dill to take her current husband on a fishing trip where her husband may fall overboard and die in a tragic “accident”. If this would happen, Karen would pay Dill a whopping $10 million! He refuses at first but eventually agrees to conspire to get Frank on his boat. And Frank turns out to be even more hateful than what Karen says about him.
This, of course, is a classic film noir set up like “Postman Always Rings Twice”, “Double Indemnity” and “Body Heat”, and you’d probably think you already know where it’s going, but writer-director Steven Knight (“Eastern Promises”, “Dirty Pretty Things”, “Locke”) has other things in mind and the narrative soon shifts in ways that you won’t see coming.

One character will be a puzzle to viewers, Reid Miller (Jeremy Strong), a businessman who’s been pursuing Dill, who seems to have a telepathic connection with his son Patrick. Reid tells Dill that he is a salesman for a fishing equipment company. But then, he reveals to Dill that he is actually a character in a video game that Patrick is playing.

After this, Patrick programs himself into the video game to be reunited with his father. So did you get it? We won’t be surprised if you’d go out of the theaters feeling perplexed or even annoyed by what you saw.
Matthew and Anne play characters that are somewhat complicated as they can easily become caricatures, but somehow, they get to hit all the right notes. Matthew plays off his character as a problematic man who screams his lungs out into the vast void of the ocean. Anne plays the femme fatale trophy wife with elan and her scenes with Matthew really work well.
Director Steven Knight uses the film as his wildly imaginative playground to craft an unusual and odd concept and treats the story with a dirty but sexy undertone that’s slightly off the wall since the characters play beautiful people in an idyllic island about to do some criminal act. If you go for unconventional out-of-the movies that will challenge you, this one is definitely right up your alley.
