The mysteries of the Sargasso Sea, or the Sea of Lost Ships, have been exciting people's minds for decades. The crew and passengers of the ship "Mara Corday", heading to French Guiana, had a change of luck, and they found themselves captives of a mysterious fog that transported them to lands where the laws of physics are in revolt and representatives of the local exotic fauna are not averse to feasting on human flesh. Unlucky sailors will have to face not only sea monsters and natural anomalies: something much more terrible, contrary to human logic, awaits them in the fog. Having given themselves up to the fight against hostile reality and their own fears, driven only by the hope of returning home, the heroes sail towards the unknown, trying not to lose the most important thing - humanity.
