Vincent's search for aliens lead him to an underwater sea lab.

The aliens take David Vincent up into their spaceship and then attempt to prove they have nothing but peaceful intentions by showing him what they've done to a desert valley. But all is not what it seems.

Vincent discovers a mysterious computer tape that could offer proof of the alien invasion.

Despite Vincent's warnings, a nurse tries to help an injured alien survivor of a saucer crash.

An old college buddy sends David Vincent an urgent message, without any further details other than that it is important. When David arrives, Ted has been brain washed so that he can no longer remember why in the world he'd wanted to see his friend. It soon becomes obvious that the aliens are using mind control of some sort.
