In the summer of 2069, five high school friends receive exciting news from the International Space Agency that their team, 'ExtraTerra V' won first place in an international science expo with a presentation called, "How to Explore the Moon's Anomalies." The grand prize is a flight to the Moon and participation in the international lunar expedition timed to coincide with the centenary of the first manned landing on the Moon. The friends plan to join other members of the expedition in Lunaris, a lunar city and main Moon outpost built ten years prior. Suddenly, a few days before the flight, they encounter a series of strange events. And before going to space to decode the Moon's riddles, they must apply a lot of effort and knowledge to solve several complex mysteries on Earth, including what hides on the 'Cursed Island' in the San Juan Island Archipelago.
