A huge solar flare is predicted to fry the Earth. Astronauts must go to the Sun to drop a talking bomb (Freddy) at the right time so the flare will point somewhere else. Giant IXL Corp CEO Teague thinks the flare won't happen and wants the mission to fail so he can buy the planet cheaply while the scare lasts. Employee Haas prepares a surprise for the astronauts. While daddy Steve Kelso commands the space ship where temperatures rise, Granddaddy Admiral Skeet Kelso is searching the desert for grandson Mike who's gone AWOL to say goodbye to his dad but who inadvertently crossed the path of the guys from IXL after meeting desert-dweller Travis.
