A guy is giving a lecture about UFOs and that the government is hiding something. Hynek is listening to the broadcast. The man in the hat is in the audience. The guy talking believes the government is preparing for an invasion.
The speaker was Mr. Keyhoe and is visited by a guy in a hat (not the hat guy) who has a story for him. The lecturer agrees to talk with the guy and pay him if it's worthy. The guy tells him about the Lubbock lights. While they're talking, a man in a hat is taking pictures.

Then Tom grabs Hynek's hand as he goes into convulsions and there's an electrical shock that is clearly visible. Something is trying to tell him something.
Mimi is cleaning up outside when she notices her neighbor's bomb shelter. The neighbor is bringing supplies into the shelter. She tells Mimi about the shelter and how easy it is to put together and how it's available at the hardware store. It's pure lunacy.

They visit Texas Tech University. Quinn goes to talk to a group of girls and asks one out after asking for directions. They head to the science and tech building and there is a roomful of people who were witnesses to the sighting. Every single one of them witnessed it. Hynek gets testimony from each one.
Hynek creates a grid - a composite sketch of the sightings to try to figure out what happened when a professor comes in who needs the classroom for his next class. He gives them a picture of the lights and proceeds to erase all of Hynek's work. The professor claims the lights were plovers.
Mimi goes into the hardware store to get information about building a bomb shelter. A man with a cap comes in and Mimi is paranoid that he's following her but then the store manager comes in and helps her destroying the feeling.

They think Hynek and Quinn are Commies. Then all the lights go out on the street and the people think the flying saucers are coming back.
Hynek and Quinn go to an empty field to wait for flying saucers. Meanwhile, Mimi is reading the instructions on how to build the bomb shelter when someone tries to get into her house through the front door. It's Susie.
For some reason, Mimi doesn't even question what Susie was doing and invites her in for tea and tells her about the bomb shelter.
Hynek and Quinn talk about the stars and how many stars there are. Quinn wants to leave and he goes to his car when it starts up by itself and things go haywire. Hynek is still outside writing notes and doesn't notice right away. When he finally does, he tries to help but Quinn warns him away and then it stops as a spaceship flies over them.
They go to the airport the next day to find out if anything happened and look at a map and try to track the spaceship and the track of blackouts that followed the flight pattern.

A guy comes into the conference room where Harding and Valentine are and yell at him for intimidating the lecturer. His name is bill and he threatens to go to the president if they don't stop.
