5 second plot: Two sisters go shark-watching (huge great white ones) in a cage. But the cable attached to the cage snaps and they end up on the bottom of the ocean. The only way up is a slow ascend while trying not to get eaten.
5 second review: If you're claustrophobic (even a little bit) I would advise against watching this movie. Because you are going to hold your breath 90% of the time. It's very tense. And they are in a cage. Deep under water. With sharks swimming above their heads. For me personally it was a bit too much of the same. But I did hold my breath 85% of the time.
