Shen Que, a surgeon at Renhe Hospital, has a cinnabar nevus on the palm of his left hand. It is said that patients who have undergone surgery by him always recover twice as fast as ordinary people after surgery. The new regular training nurse Su Wan was assigned to be his assistant. The first time she came on stage, she discovered that when Shen Que was suturing the wound, his fingertips would inadvertently rub the mole. Until one night shift, Su Wan saw Shen Que alone in the empty operating room, with his palms open in front of the shadowless lamp. The mole glowed strangely red under the cold light.
