Plot Points by Act
Act I
SetupStatus Quo
Dr. Ira Kane teaches biology at a community college in Arizona, a brilliant scientist stuck in academic obscurity after being disgraced by the Army for a failed anthrax vaccine.
Theme
Harry Block quips about adaptation and survival in their mundane academic setting, foreshadowing the theme that unconventional thinking and adaptability triumph over rigid institutional approaches.
Worldbuilding
We meet Ira Kane and geology professor Harry Block at Glen Canyon Community College. Wayne Grey, a wannabe firefighter, witnesses a meteorite crash in the Arizona desert. The scientists investigate and discover single-celled organisms in the meteor.
Disruption
Ira and Harry discover that the alien organisms are evolving at an exponential rate - millions of years of evolution occurring in hours. This could be the scientific discovery of a lifetime.
Resistance
Ira and Harry study the rapidly evolving organisms, documenting their incredible development. The military, led by General Woodman, arrives to take control of the site, citing national security. Ira's past with the Army is revealed, and he debates whether to fight the takeover.
Act II
ConfrontationFirst Threshold
Ira decides to fight back against the military takeover, refusing to let his discovery be stolen again. He and Harry commit to continuing their own investigation despite being shut out of the official operation.
Mirror World
CDC epidemiologist Allison Reed is introduced as the government's scientific liaison. Though initially an obstacle, her clumsy charm and genuine scientific curiosity mark her as a potential ally and romantic interest for Ira.
Premise
The promise of the premise delivers alien creature chaos. Flatworms evolve into insects, then reptiles, then primates. The team battles escaped creatures in a country club, a shopping mall, and suburban homes. Wayne joins the team. Allison begins sharing information with Ira's group.
Midpoint
The military reveals their plan to use napalm to destroy the underground alien ecosystem. Ira realizes this could be catastrophic but has no proof. The stakes shift from scientific discovery to preventing potential disaster.
Opposition
The team races to prove fire will make things worse while the military prepares their strike. Creatures continue escaping and evolving. Allison fully defects to Ira's team. They discover heat accelerates evolution rather than stopping it, but General Woodman proceeds anyway.
Collapse
The military's napalm attack triggers catastrophic accelerated evolution. The organisms merge into a single massive amoeba-like entity that erupts from underground, growing exponentially and threatening to consume everything. The death of hope - brute force has made everything infinitely worse.
Crisis
The team watches in horror as the massive organism grows. Conventional weapons are useless. The military is paralyzed. Everything they fought for seems lost as the creature threatens to destroy the entire region.
Act III
ResolutionSecond Threshold
Ira has his eureka moment: if the aliens are nitrogen-based (opposite of carbon-based Earth life), then selenium should be toxic to them - just as arsenic is to humans. Head & Shoulders shampoo contains selenium sulfide. Science provides the unconventional solution the military couldn't find.
Synthesis
The team commandeers a fire truck and fills it with Head & Shoulders shampoo. They must deliver the selenium directly into the creature's cell membrane. In a gross but heroic climax, Ira drives into the creature's massive opening and triggers the selenium bomb, destroying it from within.
