An expedition ship full of elite thinkers, explorers and researchers leaves the port. Among the passengers is Moi, the grandson of a professor who studies ancient civilizations. Moi’s goal is to find the ancient civilization that his grandfather, a famous history professor, had been searching for all his life. Although the professor thinks that this ancient civilization lived on the archipelagos along the ship’s route, he dies before he can make the journey. For this reason, Moi boards the expedition ship, taking all his research notes to fulfill his grandfather’s dream.
One night, the weather suddenly worsens and a storm breaks out. The ship cannot withstand the storm, and sinks. Moi opens his eyes only to find him on a beach, hungry, thirsty and exhausted. He soon realizes that he is the sole survivor. He doesn’t have much at hand, most of the supplies on the ship are lost to the sea. After collecting himself a little, he finds a cup on the shipwreck and sets out to both store some water before it gets dark and do some research. As he approaches the forest, he thinks that he might need something to defend himself after hearing the sounds of animals. He picks up the iron he finds on the ground. He tears a piece of cloth from his t-shirt and wraps the blunt side of the iron with the cloth to make a knife for himself. Then he advances into the woods.
While he thinks that there is no trace of anyone living around, he sees intertwined circle-like shapes on the trunks of some trees. Although they look like they are hand-scraped, he doesn’t care much at first and moves on. As Moi wanders in the forest, he steps on some dry branches. He thinks that the evening might be cold and that he will need fire to warm himself. He also realizes that he has to build himself a hut as soon as possible.
The sounds he hears as he progresses in the forest startle him. He thinks that he has not heard these sounds before and that this place may be a tropical island. The fruit trees he saw also support his idea. Moi trips on an object and falls to the ground while he is looking around with fear and excitement. It’s an old metal box. He picks it up and starts to examine, but no matter how hard he tries, he cannot open it. Then, he notices that the layer on the top of the box has worn off and there are some strange symbols on the bottom. He quickly wipes the remaining part with his hand and looks carefully at the box. He sees that there are 4 holes with different symbols on each of them. He realizes that these are the locks of the box. In addition, one of the symbols is very similar to the round shape he saw on tree trunks earlier.
Soon he realizes that he is on the lost ancient civilization that he and his grandfather have been researching. What he has to do now is to find food and water for his survival, craft tools to facilitate his life on the island and solve the mysteries of the lost civilization.
