An airliner taking off from LAX explodes on takeoff killing everyone except Kevin Sommers, whose entire family dies. He soon suspects sabotage, and with the help of an FBI agent he uncovers a vendetta against his father and now himself, and pursues all his would be killers. They are all stunned as he turns from the hunted into a cold blooded hunter and systematically eliminates all his enemies.
