Lisa (Mandy Moore) has just been dumped by her boyfriend for being too boring. To prove him wrong, Lisa goes on holiday to Mexico with her sister, Kate (Claire Holt). Kate convinces Lisa she needs an adventure, in the form of cage diving with deadly sharks, run by a sketchy company accompanied with two dudes they met at a bar.

In the grand cinematic tradition of Idiots Trapped in a Confined Space – see also 127 HoursBuried – the girls’ hubris means that things go wrong. After the cage’s rusty winch snaps, the sisters find themselves stuck almost fifty metres below the surface with a dwindling air supply and hungry sharks overhead. Just out of radio-range of their boat, Lisa and Kate must use their limited resources to escape their marine misadventure.
