An intelligent pulse of electricity is moving from house to house. It terrorizes the occupants by taking control of the appliances, either killing them or causing them to wreck the house in an effort to destroy it. Then it travels along the power lines to the next house, and the terror restarts. Having thus wrecked one household in a quiet neighbourhood, the pulse finds itself in the home of a boy's divorced father whom he is visiting. It gradually takes control of everything, badly injures the stepmother, and traps father and son, who must fight their way out. 一股智能电流在不同屋子间流窜。它通过控制各种器具来恐吓屋子里面的居民，或者杀死他们或者对房子进行破坏。 然后它通过电线流窜到下一个屋子，开始新一轮的恐吓行动。刚刚破坏掉一套安静的房子，电流就串到下一套住宅了。这个住宅的主人是一个离过婚的父亲和他的儿子。 在这里，电流慢慢控制了所有物体，然后重伤了孩子的继母。 现在它正在设下陷阱等待孩子和他的父亲，而他们则需要尽力找到逃生的路。。。。。。
