Alex Pruitt is a young boy who is left home alone because he is ill. At this time, four terrorists working for a North Korean terrorist group are sent by their boss to obtain a top-secret microchip that can act as a cloaking device for a missile. They succeed in retrieving the chip and hide it in a remote controlled car, but due to a luggage mix up at the airport with an old woman, the car lands in the hands of Alex who lives down the street from her and gives to him for snow-shoveling her driveway. Alex finds out about the chip in the car, and that terrorists are looking for it. So he sets up traps in his home when his house was their target.
