A space capsule crashes back to Earth near Roswell, New Mexico; Dr. Linda Murphy, answering to National Security Advisor Ethan Marcos, takes control of the investigation.

The craft is found to be from ELBE, a secret US-Soviet space program that aimed to end the Cold War by establishing a joint first contact.

Linda trips and is knocked unconscious, but sees another team led by her former classmate Eva Kuleshov, who is now a Russian agent, arrive and tranquilize Abraham.

Back at the crash site, a group of soldiers left to guard the capsule are killed by the now-mutated, gigantic Dinosaur-like Gila.

Meanwhile, Eva discovers that the alien substance breaks down in Earth's atmosphere, leading her to covertly have the entire remaining supply injected into Abraham to stabilize it.

They track Abraham to Huntington, West Virginia, where Linda discovers the substance breaking down in blood he left behind, forcing Eva to admit her deception.

Returning to Langley, Linda and Jones discover beams of cosmic energy transmitted from the Andromeda Galaxy are remotely controlling both monsters via the substance in their bodies.

The Hubble Space Telescope discovers an alien ship approaching Earth, forcing Marcos to call Noah in to provide assistance.

The transmitter is attached to the Washington Monument shortly before Abraham appears in the city, guided there to decapitate the U.S. government in preparation for a full-scale invasion.

In it, the United States military creates a giant mechanical ape, but it escapes and wreaks havoc, leading them to release the captive Abraham to neutralize the threat before it destroys downtown Chicago.
