When a mother is informed by the rescue team that, as her 7-year old twins are buried under the debris close to each other, digging one out would result in further collapse of the wreckage on the other, she is forced to make the most difficult decision of her life. As the clock ticked away, she finally ended her struggle and chose to save the boy, and though heartbroken, she had no idea her decision was overheard by the daughter. Deemed as a dead person, the little girl miraculously survived and was rescued after being buried under for days. Suffering from the emotional shock of the disaster and the painful memory of her mother's choice, she refused to reveal whom she was. She was adopted by a young couple and later moved to the US, but shadowed by the traumatic experience from her childhood, she forever remained emotionally closed up.
