A girl named Yuria went missing at age 13. Thirteen years later, she suddenly returns to her family, only to find that their world has completely changed and her family is broken apart. Her return begins to alter the fates of those around her.

Her mother, who has been crushed between regret over losing her daughter and hope for her return, must now face her hidden past beneath the joy of reunion. Her father and sister, while pretending to be a happy family for Yuria’s recovery, are forced to reexamine their separate journeys over the past 13 years.

 

Yuria tells police she was kidnapped. But what happened during those 13 years? The investigating detectives struggle with doubts about her testimony, which keeps changing and contains contradictions. Then a second incident occurs! As Yuria’s hidden truths come to light, the family’s own buried secrets begin to surface…

 

Based on BBC’s “Thirteen,” which became a massive hit in the UK, attracting 7.95 million viewers (approximately one in eight Britons) who requested to watch it. After its first episode aired, it topped the BBC’s catch-up viewing charts across all programs.

 

The Japanese adaptation maintains the original’s suspense while focusing more deeply on each family member’s story.
