The four trainees are back, with a new supervisor who was hired to judge if they pass or if they still need training. This time, Aizawa rescues a child that was lying in the water for more than half an hour. He managed to reanimate him, but they don't know how much damage his brain suffered. Hiyama seems to start having problems with her heart and Saejima lives in her bitter-sweet relationship with her not curable boyfriend.

Hiyama is still suffering from her heart operation and wonders if she should let her heart be tested. Shiaishi tries to fly with the heli more that the other ones, never forgetting what Dr. Kuroda told her. Fujikawa has to realize that he also cannot save everyone when he loses someone on the scene after trying his best. What beats him the most is that if Aizawa had been on the heli, he might have been able to rescue the man. However, Aizawa tells him, that he also lost people this week.

A huge accident happened at a train station. Shiaishi is in charge for the tagging while all the other senior doctors and Aizawa are needed for 3 people that crashed on the stairs, a ski sticking through the body of the two people on top. There is only the possibility to save two out of three. Hiyama decides for an operation on her heart. At the end of the episode, Aizawa's father seems to be alive.

Hiyama discovers that Shiaishi had done a mistake in the previous night duty that was life threatening for a patient. She is told by her boss to take a break once in a while and Hiyama tells her that she shouldn't take all the work on her, but that they can do it together. A bit later, they perform a surgery together as none of the seniors is available which strengthens their bond. Aizawa has to deal with a young girl who's pregnant but doesn't want to have the baby.

This episode was about the death of Saejima's boyfriend who was once a doctor too and her tutor, but suffered from an illness that wasn't curable. He refrained from treatments that would extend his life, so he left his body to die out of its own will. However, when it happened, Saejima was on flight with the heli. Aizawa was dealing with a 7 year old child out of the orphanage. Due to his own history he was able to understand her and gain her trust.

A brain dead child is lying in the ICU and it's Hiyama's task to inform the mother and ask her to sign and give the okay to stop the machines. However, Hiyama gets too much involved (emotionally) and removes the breathing tube, causing the boy to die. The uncle of the boy is therefore talking to a lawyer. Aizawa talks to his father and has to get to know that his mother committed suicide because she didn't want to raise him anymore and Shiraishi learns that her father has lung cancer.

Hiyama's situation gets worse. The uncle brings the case up in front of the court and she gets suspended from working on a patient. Aizawa goes to have a talk with his father, wnating to know more about his mom, but leaves his dad furiously. Seajima forgets to pack an important tool into the bag on the heli, which brings some trouble to Aizawa and Shiraishi. Fujikawa tries his best to help her out of her gloomy thougts and slowly manages to break through her shell.
