“Something strange is going on on this liner!” – photographer Agniya Tumanova reflects. On a magnificent ship, where representatives of business circles, including her fiancé Daniil Verbitsky, decided to hold a business forum, firstly, all the CCTV cameras suddenly turned off, and secondly, a waiter makes an unsuccessful attempt on the life of the wife of one of the entrepreneurs. And soon rich women - the wives and daughters of businessmen who went on a cruise - begin to die mysteriously. Agnia has already promised a million times not to get involved in criminal stories, but how can she resist when they are in the middle of the ocean, there are bloodthirsty sharks overboard - and a crazy maniac is wandering around on board. Or maybe not even a maniac, but one well-known “maniac”?..
