Saucer: Savage Planet

Aliens are coming.
A year after young engineering student Rip Cantrell discovered the first flying saucer buried deep in the sands of the Sahara, another saucer is brought up from the bottom of the Atlantic. The recovery is funded by a pharmaceutical executive who believes that the saucer holds the key to an anti-aging drug formula that space travelers would need to voyage between galaxies. But one of his technicians, Adam Solo, an alien marooned on Earth for a thousand years, steals the saucer, hoping to summon a starship to rescue him. Unfortunately, the stolen saucer has damaged communications gear.
Solo goes to Rip Cantrell and his partner, ex-Air Force test pilot Charlotte "Charley" Pine, and Rip's uncle Egg, for help in summoning a starship. Meanwhile, as a terrified world fearful of space invaders approaches meltdown, big pharma moguls and their thugs are hot on the trail of the foursome.
In a world turned upside down, it may be the arriving aliens who offer limitless possibilities. Rip and Charley face an incredible decision: Do they dare leave the safety of earth to travel into the great wilderness of the universe?
