47 Meters Down

“No way out. No way up. No chance in hell.”

Lisa (Mandy Moore) is on holiday in Mexico and wants to prove to herself, and to her sister Kate (Claire Holt), that she isn't the dull one. So she agrees to go down in a shark cage, and the winch holding it gives out, dropping them to the ocean floor with less than an hour of air and great whites circling. Johannes Roberts keeps the camera inside the cage with them, so the only view is through the bars.
