In 1846, a merchant ship was shipwrecked off the coast of Scotland in the night, stumbling upon an unknown underwater object in the dark. Survived only three people who managed to escape in a small boat. Being completely disoriented, they tried to check with the map in order to understand where to row, but they suspected that the ship had drifted into unknown waters. Soon the morning fog cleared and a lonely island appeared on the horizon. Men could not hold back their happiness, having begun to swim swiftly toward the cherished land. Frozen, hungry, but wildly joyful, they climbed onto the rocky shore, starting to look for firewood for the fire.
Soon they were discovered by a respectable old man Fingal Mcleod, who offered them to rest at his home. In the morning he took them to farmer Douglas Innis and his niece, Lanta, so that they could heal the wound to one of the sailors. On the way, they were attacked by a recluse who first saw people, but an elderly man drove her away, saying that she was under stress because of her brother’s death. The main characters are aware that only four people live on a mysterious island and they all behave strangely. All their attempts to reach the mainland turn into a complete failure. A piece of land at sea becomes their prison, but soon there is still a greater threat in the form of mythical sirens in the form of beautiful maidens, whose songs carry mortal danger.
