The special task force in the film is responsible for tracking the whereabouts of aliens and recording their actions. Everyone in the action group is dressed in black and wearing a black tie, which is more solemn than Washington officials and Wall Street tycoons. The veteran of the action group, code-named Lao K, never smiles. In order to enhance the combat effectiveness, the superior sent him a young assistant, code-named little J. An alien UFO crashed into Edgar's truck and attached to him like a ghost. This "occupied" Edgar must conquer the earth with an occupied constellation.
