GDF Captain Ridley O'Bannon sends out a distress call during a routine inspection of the derelict generation ship known as EDEN (intended to travel the stars for hundreds of years). John and Alan answer the call. Together, the trio explores the ship and discovers leftover equipment known as Builder Bots. They also find two space "pirates" named Reece and Dobbs causing mischief. As the mystery comes to an end, the pirates accidentally reverse the bots' programming, causing them to tear EDEN apart. With the help of John's Mech Suit, they escape.
