For more than 50 years, World War III had spread across the country, eventually reaching Indonesia—the birthplace of Lindsey, a girl who was born and abandoned upstream, where she met an elderly man who took her in.

After peace returned to the world, Lindsey found a home in the Houdoug complex alongside her grandfather—Yolan. However, the landlord of Houdoug, a veteran police officer, grew suspicious of Lindsey’s activities related to the end of World War III.

Does this mean Lindsey can live in peace? Of course not. After Yolan’s death, a series of murders occurs, forcing Lindsey to become a detective in order to find peace. These are no ordinary murders; they involve many different killers, yet are believed to be orchestrated by a single mastermind.

Will Lindsey succeed in finding him? Will her past be revealed? And more importantly, will she be able to live in peace?
