Ben (Josh Lucas), Kayla (Jessica Biel) and Henry (Jamie Foxx) are all top pilots. On this day, they received a secret mission: to train their new partner "Iron Egg". Unexpectedly, "Iron Egg" turned out to be a fully intelligent unmanned aircraft, and their mission was to train it to be a sharp knife. After completing a flight mission, "Iron Egg" was accidentally struck by lightning, and "Iron Egg" therefore had emotional autonomy. In the subsequent mission, the headquarters considered the situation at the time and planned to abandon the mission. Unexpectedly, "Iron Egg" suddenly flew away from the formation and dropped a ground-penetrating bomb into the enemy's nuclear arsenal, causing an unprecedented nuclear disaster. Captain Ben realized that such an intelligent killing machine must be destroyed immediately, otherwise it would bring more disasters to mankind, and he immediately reported to the headquarters. The smart "Iron Egg" learned of their actions, and a man-machine chase began!
