Mia is uneasy in her new environment and detects inconsistencies, such as her childhood room appearing too young for her age. One day, while shopping, Mia notices a milk container with her portrait labeled “MISSING.”

Mia finds Laura’s mental illness and believes Mia is her deceased daughter. Finally, Mia escapes with the help of the police, meeting with her true parents who had been looking for her.
