A ferry filled with crewmen from the USS Nimitz and their families was
blown up in New Orleans on Mardi Gras. BATF Doug Carlin is brought in to
assist in the massive investigation, and gets attached to an
experimental FBI surveillance unit, one that uses spacefolding
technology to directly look back a little over four days into the past.
While tracking down the bomber, Carlin gets an idea in his head: could
they use the device to actually travel back in time and not only prevent
the bombing but also the murder of a local woman whose truck was used
in the bombing?
