Fate takes their lives in different directions, until two government agents visited the Hunter home years later.
A promise to walk again to run, to even fly, is too good for Joe to refuse, and Frank, in time, with super-hero like skills akin to Joe's, joins the adventure.

The secret mission blasts open the door to a confrontation with alien beings, and Earthly adversaries to a final battle for possession of ancient flying machine.
Who will be victorious?
The fate of humankind is now threatened.
