In the turbulent final years of Indonesia's New Order, 1998, a generation of young idealists risked everything for the dream of freedom. Among them is Biru Laut, a university student whose passion for justice and belief in democracy draws him into a secret circle of activists known as the Winatra group. The story follows the disappearance of Biru Laut and the subsequent search for him and other student activists by his family, particularly his younger sister Asmara Jati, revealing a dark period of Indonesian history marked by violence and the struggle for democracy.
