As The Hitchhiker's Guide to the Galaxy opens, main character Arthur Dent is faced with a rather significant challenge - bulldozers preparing to tear down his house in order to construct a highway bypass. He does his best to fight this demolition, refusing to vacate the premises and arguing that adequate notice was not given. Unfortunately for Dent, there is no turning back with the plans for demolishing his house, as this is not just any highway construction project. Aliens are preparing to move to the next stage of their invasion of Earth. Some, including Arthur's friend Ford Prefect, have been on Earth for years becoming familiar with the planet and its possibilities, and now they are proceeding with the next step in their plan.
In the beginning, Arthur Dent is faced with a dilemma created by the city council. They want to build a bypass which would mean destroying his house. When he complains they argue that the plans were " on display " in the basement of the city council office the whole time and that if he really cared, he would've said something earlier.
