In case you have forgotten, 'The Shallows' serves up plenty of scares. The film follows grieving medical student Nancy Adams (Blake Lively) who heads to a secluded beach in Mexico to brave the waves her mother, who recently passed, once surfed.
Suddenly, a ridiculously big great white shark attacks and forces Nancy to swim to a tiny rock 200 metres from shore. Stranded, alone and freezing she fights for her life as she battles the beast circling her.
