Temporarily Detained

The prototype of a TTD is on the body of its inventor. Does his captors know or do they just want him to create another one so they can mass produce it and sell it to foreign enemies. A Temporary Transient Device can help save lives. In the wrong hands, it can immobilize an army.
An unplanned plane ride for the inventor, puts the whole civilized world in jeopardy. But the genuis has also been blessed with instinct and fortitude. His skills might keep him safe but will it fall into the hands of U.S. enemies? He will succeed or die trying.
