Ichiko (Tsutsui Mariko) is a kind nurse who is responsible for taking care of an old man named Tachiko who is in the terminal stage of cancer. Motoko (Ichikawa Miko) is Tachiko's daughter. The relationship between her and her family was once very tense. Because of Ichiko's intervention and adjustment, Motoko gradually eased the parent-child relationship and found the direction of future efforts. She hopes that she can become a nurse as gentle and kind as Ichiko. Motoko's sister Saki (Ogawa Misuke) was involved in a kidnapping incident and became a hostage. She was not rescued from captivity until a week later. What Ichiko didn't expect was that the kidnapper was not someone else, but her nephew Tatsuo (Sudo Ren). Motoko and Ichiko reached a consensus and decided not to tell Tachiko about this matter, but when Motoko learned that Ichiko was about to marry someone else, jealousy and anger overwhelmed her mind and made her make irreversible moves.
