What starts as a pleasant class trip to a planet five light-years away becomes a nightmare survival trip to get back home. In the year 2063, interstellar space travel has become the norm. What sort of adventure awaits on the new frontier? The situation aboard the Astra intensifies as Zack reveals to Kanata that the ship's communication system has recently been sabotaged and that it's likely one of their new friends who tried to murder them! The mystery deepens as the crew members are overtaken by confusion and anger and start to question each other's motives. Just as the argument comes to a head, the side of the ship explodes, shutting down the controls and gravity system and setting the Astra on a collision course with the second planet on their trip, Shummoor.
