The early part of the film follows the experience of a late 19th-century journalist from Woking, known as "the writer", involved with the landing of a Martian invasion spacecraft. When the crashed cylinder opens, the Martians start killing anything that moves with a "heat ray" weapon. The writer discovers his house is in range of their heat ray and decides to rush his wife and servant to her cousins' home in Leatherhead; once there, he returns in order to return the borrowed cart to its owner, unaware that the invading Martians are now on the move.
The Martians have built tall tripod "fighting machines" and begun a destructive rampage across southern England. The film also details the adventures of his brother, a student in London, who accompanies two ladies to the east coast of England in order to escape the slaughter and destruction by the Martians.
When the writer tries to get back to his wife in Leatherhead, he is confounded and beset by many problems as a result of the chaos wrought by the Martian invasion.
