When it comes to the ocean, there’s nothing worse than being out on open water and realising you’re not alone…

Mia (Blake Lively) is a seasoned surfer, experienced at riding the waves in all sorts of conditions. When she grabs her board and heads to the beach, seeking escape from recent tragedies that have plagued her life, she expects nothing more than the sweet release of being one with the wind and water.

What she doesn’t know is that this time evil lurks beneath the jewel-coloured waves.

A sudden shark attack leaves Mia floundering in crisis. In a fit of luck and quick thinking, she manages to scramble out of the water and finds refuge on a sliver of rock.

The beach is only 200 yards away – but with the great white monster waiting somewhere between her and the shore, it might as well be 200 miles…

Stranded in the sea, with nobody to hear her screams and the giant predator waiting to strike, Mia begins to wonder if she will ever reach land again…

The latest from horror-mogul director Jaume Collet-Serra (The Orphan), this suspenseful story outlines the struggle between woman versus wild and stars Lively (Gossip Girl) alongside Óscar Jaenada (Pirates of the Caribbean).
