People love sharks in horror movies. That's why there are so many 'Jaws' films, and also why someone made the questionable decision to make 'Sharknado'. As well as that, it's also the reason why there's a sequel to '47 Meters Down' coming out on 28th June 2019. The original wasn't a favorite among film critics but making ten times its budget at the box office always meant that a follow up was inevitable.
The same writer, producer and director are on board, but none of the original cast are back; mostly because they're either dead or have presumably learned not to dive into shark infested waters. A new cast of young women do exactly that off the coat of Brazil and are in for a nasty surprise as they attempt to explore some underwater ruins. We expect that nasty surprise to consist of several hungry sharks.
