The official synopsis for the film is as follows:
Baker Dill is a fishing boat captain leading tours off a tranquil, tropical enclave called Plymouth Island. His quiet life is shattered, however, when his ex-wife Karen tracks him down with a desperate plea for help. She begs Dill to save her – and their young son – from her new, violent husband by taking him out to sea on a fishing excursion, only to throw him to the sharks and leave him for dead. Karen’s appearance thrusts Dill back into a life he’d tried to forget, and as he struggles between right and wrong, his world is plunged into a new reality that may not be all that it seems.
Directed by Steven Knight, Serenity stars Matthew McConaughey, Anne Hathaway, Diane Lane, Djimon Hounsou, Jason Clarke and Jeremy Strong.
The film is scheduled for cinematic release on the 25th January 2019.
