THE SHALLOWS Trailer (2016)

Shortly after the death of her mother, medical student Nancy Adams (Blake Lively) travels to a secluded beach in Mexico to surf, which is also the same beach her mother surfed at after finding out she was pregnant with Nancy many years before. Nancy gets a ride to the beach from Carlos (Óscar Jaenada), a friendly local resident, who refuses to tell her the beach's name, saying only that it is paradise. After arriving at the beach, Nancy joins two other local residents, and the three surf for several hours.

Taking a break from surfing, Nancy video-chats her sister Chloe (Sedona Legge) to let her know that she is surfing at their mother's beach. When she talks to her father (Brett Cullen), it is revealed that her mother's death has caused Nancy to consider dropping out of medical school. The conversation becomes emotional and strained, and Nancy hangs up to catch one more wave in the late afternoon before heading back to her hotel. While waiting for a wave, Nancy notices a large whale carcass floating about twenty yards away. 

While riding a wave back to the beach, a large great white shark bumps her surf board, causing her to fall and hit her head on a submerged rock formation. As she surfaces to her board, the shark bites her leg, pulling her under. Nancy crawls onto the whale carcass, where she stays until the shark rams it from underneath. Nancy swims to an isolated reef, where she places a tourniquet on her leg to stop the bleeding. The two locals depart, unaware of Nancy's situation, leaving Nancy to spend the night on the reef.

The next morning, Nancy sees a drunk local man passed out on the beach. She gets his attention, but he proceeds to steal her phone, money, and backpack. After noticing her surfboard floating in shallow water, he wades out to retrieve it, only to be torn in half by the shark. Several hours later, the two locals Nancy had surfed with the day before return. They get into the water before Nancy can warn them away, and both are killed by the shark. Nancy retrieves one of the men's GoPro camera helmet, and records a message for her father and sister, and then throws the helmet toward the shore.

With high tide approaching, Nancy knows the reef will be submerged soon. After timing the shark's circles from the whale carcass to the reef, Nancy swims to a nearby buoy, narrowly avoiding the shark by swimming through a group of jellyfish, which sting both the shark and Nancy. Nancy is able to find a flare gun on the buoy, but cannot catch the attention of a passing cargo ship farther out to sea. Nancy shoots at the shark, which catches on fire because of all the whale blubber in the water. The shark begins furiously attacking the buoy, ripping out one of the chains securing it to the ocean bed. Nancy grabs onto the remaining chain. When it also breaks, she lets it pull her down to the ocean floor. The shark pursues Nancy down as fast as possible and is killed when it impales itself on the metal rods of the buoy's mooring.

The GoPro camera is found floating near the shore by Carlos' son who brings his father to the beach. Carlos then finds Nancy floating in the shallows as his son runs for help.

One year later, Nancy and Chloe are going surfing in Galveston, Texas as her father tells her that her mother would have been proud.
