 The Rangers return to Earth, and attempt to bond better with alien Andros, who s bemused by our strange culture. Unfortunately, our heroes also get an unfriendly welcome from Astronema who has followed them there (along with her new henchman Elgar), and not only unleashes her cohort Ecliptor on them, but fires upon NASADA, intent on destroying the Shuttle! Meanwhile, Bulk & Skull seek to prove conclusively, without a single doubt, once and for all that aliens exist and are currently targeting Earth (and in the process become rich & famous). To do so, they team-up with a nutty old scientist named Professor Phenomenus. First stop in their quest, NASADA... where they encounter Quantrons!
