This drama is about Han Saet Byul, a 9 years old girl, and her mother, Kim Soo Hyun (played by a GREAT Lee Bo Young). After her daughter is kidnapped and murdered, Soo Hyun is able to travel 14 days back in the past and repet the last days with her daughter from the beginning. She will try to save Sae Byul and catch the killer with the help of Ki Dong Chan, a private inspector. I really enjoyed this drama: interesting plot, great acting and thrilling atmosphere! Lee Bo Young is really good while crying and playing an anxious yet determinated mother. In my opinion I won't rewatch it because I'd alreay know who the killer is and why XD
