The year is 2132. The resources on Earth have become depleted, and mankind sought out new settlements and advanced on to other planets. At that time, a meteorite from space has been detected carrying unicellular organisms with similar DNA structures as those found on Earth. This discovery is thought to contain the key to unlocking the mystery behind the origin of life on Earth, so an investigation has been launched. As a result, an unknown planet has been discovered in our Solar System: Harmonia. An American research team from Mars Base is set out to embark for Harmonia in order to survey it. Soon the truths behind mankind, life, and the universe will be revealed.
