Having bought vouchers for the ship "Ramses", which is going on a cruise on the Nile, girlfriends Marina and Alina were looking forward to an exciting trip to exotic places. But their old friend Oksana, who also booked a cabin on the Ramses, pursued, as it turned out, completely different goals - she decided to ruin the honeymoon trip for her ex-husband Vasily and his new wife Rada. What I did with pleasure and in the restaurant, and on the deck, and on excursions. Therefore, when Vasily was found lying in a sun lounger with a knife wound in the heart, almost no one had any doubts: the killer was Oksana, because she had a motive. Only Marina and Alina believed their friend and undertook to prove her innocence. And there are only a few days left until the end of the cruise!
