Space flight is possible and commercially available in 2063. A daring burglar steals the cheery Aries Spring's pocketbook as she arrives at the spaceport to attend a camp on the faraway planet McPa. Fortunately, the athletic Kanata Hoshijima is able to grab it for her, and Aries soon realizes that he is one of the youngsters that will be coming with her on the adventure as team B-5. The group's adventure takes a turn for the worst when they arrive at their campground and are sucked into the wide depths of outer space by a weird orb of black light. They are stranded with apparently little hope until they come across an abandoned ship nearby that supplies them with a method of returning home.
