As adventurers of the grand cosmos, Mr. Jason Space and Captain Helena Galaxy seek to discover new worlds and new adventures and to have fun while doing it. They will never do paid mercenary work, no matter how good the offer, for they are explorers and not mercenaries. They will complete every mission they undertake, no matter how much trouble it gets them into. And they will never give up, regardless of whatever menacing aliens or dangerous obstacles they run into.In order to earn more money to fuel their adventures, Galaxy and Space travel to the jungles of Shizor in search of ancient ruins that might hold valuable artifacts that they can sell to museums. But with Galaxy suffering from sleep deprivation, the two explorers must escape the ruins before the mysterious Phantom of the Jungle claims both of their lives.
