A team of federal investigators have to comb through the wreckage of a crashed airplane to find the cause of the fatal downing. Was it terrorism? Negligence? Human failure? Or just a tragic accident?

Flight 323 from Burbank, California of Hub Weber's Commonwealth Airlines crashes after an explosion over Nebraska. National Transport Security (NBSC) chief Reese Faulkner hands the investigation team for the first time to perfectionist workaholic Al Cummings, but has to supervise his PR incompetence. Aboard were a Nobel Prize winner who received death threats, an FBI-conducted criminal and a mobster who smuggled a victim in trunk. The team also examines possible pilot errors or technical trouble. Meanwhile Al has a conflict with his son Pete, whose drivers license was suspended.—KGF Vissers
