Meet Ben Darnell, a father who remembers his own tragedy...

Meet Major Ben Darnell, Army physicist

"So what the heck is THAT?  A prairie in a box?  Out here?   In the desert? 

Maj. Holman briefs Darnell on the window.

Maj. Darnell builds a model to study the phenomenon.

Ben watches the prairie people living in their universe.                  

Darnell comes up with a theory about how to breach the barrier.

Ben delights in his discovery.

Watching & waiting for a clue, a break through in the mystery comes at a most unexpected moment.             

One of those "Ah-ha!" moments; Ben hits upon an ingenious solution.

Ben enters data collected on the prairie people and the conditions about the barrier.  So why is he keeping it a secret?

Ben watches her wistfully, perhaps with affection.
