She then sees the shark attack the man as he heads back to the shore. Nancy yells to him to get away from the shark. He sees her board floating in the shallows and he walks into the water to get it. The man just steals her phone and wallet. Nancy points toward her bag for her to call for help. She calls out to him and manages to get his attention. On the shore, she sees a drunk man passed out in the sand. Nancy tries to eat a tiny crawling creature, but she quickly barfs it up. Her only companion is a seagull with an injured wing. It starts getting darker as Nancy tries to get an opening away from the shark. Nancy sees the other two surfers and tries calling to them for help, but they don't appear to hear or see her. She takes the ankle strap from her board and uses it as a tourniquet to stop the bleeding.

Nancy struggles to escape and swims to a rock where the shark can't reach her. Nancy climbs back on and tries to paddle back, but the shark bites deep into her left leg, spilling a lot of blood into the water. Sensing trouble, Nancy tries to head back to the shore on a wave, but as she rides it, a large great white shark slams into her and knocks her off the board. As she gets further from the shore, she sees a whale carcass floating up top. Nancy swims out past the shallows of the ocean to catch some more waves. He expresses concern to Nancy over her grief and actions. Nancy then talks to her father (Brett Cullen), who knows she is taking the trip for her mother. Later, Nancy has a video chat with her sister Chloe (Sedona Legge) to tell her all about the beach and how their mother was right about how it's like paradise. Nancy joins the two of them as the waves get nicer. She comes across two other surfers who know she is a visitor. Nancy gets into her surf gear and hits the waves on her board. She offers him some cash for his services, but he declines. She is supposed to be there with her friend Anna, but she claims to have gotten sick, leaving Nancy to take the trip alone.
Nancy is driven there by a man named Carlos (Oscar Jaenada). The beach was a favorite spot of her mother, who recently passed away from cancer. Nancy Adams (Blake Lively) is a college medical student headed toward a beach for a personal vacation.The synopsis below may give away important plot points. However, has anyone escaped from the powerful and razor-sharp jaws of the blood-thirsty leviathan? Now-atop a small rock protrusion, a mere 180 metres from the shore-it's woman against nature, in a desperate battle of survival under the scorching sun and the cold starry sky. Indeed, this is the perfect hideaway-and as Nancy rides the glorious waves, one after another-a silent and sudden attack from below throws the gravely wounded holidaymaker into the water, reminding her that this is the realm of a feared apex-predator: the slate-grey great white shark. Still unable to come to terms with a personal tragedy, Nancy, a medical school dropout and athletic surfer, seeks solace in her late mother's secret surfing spot in sun-drenched Baja California. Alone and wounded, she attempts to survive the attack and get ashore. While paddling out into the waves along with two other friendly locals, she is hunted by a great white shark and stranded on an embankment away from the shoreline. Shortly after the death of her mother, the medical student and young surfer Nancy ( Blake Lively) travels to a secluded beach in Baja California in search of a secret spot that her mother had discovered years earlier.
