At the beginning of the nineteenth century, a ship sailing from Java toward the Sunda Islands is caught in a violent storm. Its unnamed passenger finds himself among people struggling to survive far from familiar shores. Against the vast, dark ocean, the voyage becomes an encounter with isolation, fear, and the limits of human understanding. Through the traveler’s written account, ordinary expectations give way to unsettling uncertainty, while the sea’s power and the strange events aboard the vessel shape a growing sense of danger.
