“On Plymouth Island, no one ever dies… unless you break the rules”

Baker Dill (Matthew McConaughey) runs a fishing charter off Plymouth Island and wants one thing, a giant tuna that keeps slipping his line. His ex-wife Karen (Anne Hathaway) turns up with a request that has nothing to do with fishing, involving her new husband Frank (Jason Clarke). Steven Knight sets Baker's obsession against her offer, and the island is small enough that nobody there can stay out of it.
