The guys arrive in a brick basement on the North Atlantic coast in 1978. It has advanced electrical equipment, and they are attacked by an overalled man. He collapses dead, then gets up and disappears in a cloud of smoke. They go upstairs and are paralyzed by an alien-android disguised as an old woman. The aliens are preparing to steal Earth's oxygen. The Project staff execute a lateral transfer and free the guys.
