In 2075, the depletion of natural resources has devastated Earth, and an elite team is sent on a special mission to an abandoned research base on the moon. On Christmas Eve, astrobiologist Song Ji-an just landed on the moon. She is part of an elite team sent to the moon on a mission to save the planet from depleted natural resources. For humans, the moon is still an infinitely mysterious place, and many fields are unknown.
While searching for clues to save Earth, team members are caught up in the mysterious predicaments and unforeseen events of outer space. Their fate hangs by a thread... Chief Choi's introduction to the mission makes Song Ji An uneasy. For the players, just getting to the base is not easy. The team's initial findings were at odds with what they knew about the base. The players were divided into three groups and began to look for samples. An astonishing moment of life and death is captured on Ji-an's body cam. Kong, who was covered in sweat, showed symptoms of a special infection, which was very worrying.
Han Yoon-jae reported the new situation to the director and entered the control area. The team learned about the power of the samples and the real motivation behind their mission. Ji-an retrieves her sister's encrypted information and starts searching for Luna in the database. A young intruder and a perfidious man show their true faces.
E2, Ryu Tae-seok, and the sample are all gone. After seeing a familiar name on the intruder, Ji-an follows her to the vent to find out. Ji-an opened a hard drive that recorded Song Won-kyung's life and work at the base. Meanwhile, others found remnants of the experiment. With the base destroyed, the surviving members race against time to decide the mission and their own destiny.
