A mysterious meteor crashes in the arid landscape near Glen Canyon, Arizona, causing chaos. The impact is so profound that it even lands directly on the car of fireman trainee Wayne Grey, who is conducting fire safety drills.

Ira Kane, a biology professor, faces challenges with his students at Glen Canyon Community College. Among them, Deke and Danny stand out as the least knowledgeable, frustrating Ira and pushing him to seek more worthy academic pursuits.

The day after the crash, Ira and his geology colleague Harry Block head to the crash site after receiving urgent news. They are joined by Nadine, a student eager for extra credit, showcasing her determination to succeed.

Upon arrival at the crash site, Wayne reveals that the meteor is deep within underground tunnels. They collect a glowing blue liquid sample, which contains alien microorganisms that evolve rapidly, multiplying into complex organisms in just hours.

Intrigued by their discovery, Ira and Harry observe the swift evolution occurring in the samples. They realize that the rapid development typically takes millions of years, which only fuels their determination to keep the findings private from the government.

As tensions rise regarding the meteor, Wayne grapples with his training, failing a critical test. He also works as a pool manager, where he unexpectedly encounters unusual creatures in the water supply room that hint at the ongoing alien activities.

General Russell Woodman and Colonel Flemming arrive with military forces to assess the situation. Ira and Harry see this as a threat to their research, sparking a conflict over their rights to study the aliens.

In a dramatic turn, Ira and Harry face off in court against Dr. Allison Reed, who shows little concern for their groundbreaking findings. Their irritation grows as Ira's controversial military past comes to light amidst the court proceedings.

While the professors and Wayne explore alien adaptations, a newly-emerged creature disrupts a local mall, causing widespread panic. Wayne cleverly utilizes the mall's sound system to lure the monster away from the terrified shoppers.

With the situation spiraling out of control, officials strategize to contain the alien outbreak. The group find themselves confronting alien primates while also dodging a planned napalm strike aimed at eradicating the growing threat.

In a desperate bid to combat the alien menace, the group devises a plan to use selenium, a poison effective against the nitrogen-based aliens. They adapt Head & Shoulders shampoo as a creative weapon to aid in their struggle.

The final confrontation against the rapidly evolving alien mass unfolds in a high-stakes battle. Through teamwork and ingenuity, they manage to execute a daring maneuver to neutralize the colossal organism threatening the nation.

After successfully defeating the alien threat, the group receives accolades from Governor Lewis. Ira, Harry, Wayne, and Allison are hailed as heroes, celebrating their triumph against overwhelming adversity.

The story concludes with a light-hearted touch as Ira and Allison share a romantic moment following their victory. Meanwhile, Wayne enjoys his newfound reputation as a firefighter, wrapping up a chaotic yet thrilling adventure.
