Harrison and the team talk to a psychic woman who studied the aliens after the first invasion. Meanwhile, a group of aliens take over a family and travel cross country in order to awaken more aliens from hibernation.

The team is sent to Grover's Mill when it is discovered the 1938 radio broadcast of invasion was real. They meet with a group of local men who successfully fought the Martians 50 years ago and believe the Martians have returned to try and retrieve weapons abandoned in 1938.
