Salvaging the material and technology from the spaceship crash at Roswell, the NSA secretly develops a spherical time-ship that has the limited ability to send one person back in time, up to seven days. Called 'Project Backstep', it is reserved for selective use, only to undo significant, recent, disastrous events. The pilot, or chrononaut, of the 'sphere', is a Lt. Frank Parker. An ex-Navy SEAL with a loose-cannon/free-spirit quality, he is supported by a vast staff of technicians and a few main character specialists. Not only do they deal with correcting disasters, but also the only-slightly-better-than-crude, theoretical, patch-work, barely-understood execution of time travel.
