When Nancy seeks out a secluded beach that her mother had told her to visit, everything seems perfect, but when a shark enters ‘The Shallows’, she finds herself stranded. She’s stuck on a rock 200 yards from shore. The other surfers nearby have been killed. Escape seems impossible. It’s only a short way to safety, but she can’t possibly swim faster than a shark, forcing her into a battle of wills and ingenuity in order to survive. A white-knuckle thriller starring Blake Lively, be careful – you never know what could be beneath the surface.
