Story Structure — 5 Plot Phases
The Virus Escapes
A covert MM88 transaction ends in a transport-plane crash and accidental release. The Italian Flu rapidly becomes a worldwide pandemic.
Key Events
-
MM88 Transaction — A scientist and American buyers conduct a covert transaction involving the deadly MM88 substance.
Location: East Germany
-
The MM88 Virus — MM88 amplifies any virus or bacterium it contacts, making it exceptionally dangerous.
Location: Laboratory
-
Transport Plane Crash — The plane carrying the recovered MM88 crashes, causing the virus to escape.
Location: Crash Site
-
Pandemic Begins — The released virus spreads worldwide and becomes known as the Italian Flu.
Location: Italy
-
Global Population Collapse — Within seven months, virtually the entire human population dies from the pandemic.
Location: Worldwide
Antarctica Endures
Cold temperatures protect the Antarctic population from the inactive virus. An infected Soviet submarine creates a dangerous confrontation near Palmer Station.
Key Events
-
Cold Stops the Virus — The virus becomes inactive below minus ten degrees Celsius, sparing people in Antarctica.
Location: Antarctica
-
Antarctic Survivors — Eight women and 855 men remain alive in the Antarctic polar winter.
Location: Palmer Station
-
Infected Submarine Approach — An infected Soviet submarine attempts to approach the Antarctic station.
Location: Near Palmer Station
-
Nereid Sinks Submarine — The British submarine HMS Nereid sinks the infected Soviet submarine before it reaches land.
Location: Antarctic waters
-
Survivors Join Forces — The British submarine joins the Antarctic scientists and survivors.
Location: Palmer Station
A Fragile New World
The survivors begin rebuilding society several years after the pandemic. The discovery of the earthquake-triggered ARS threatens their fragile future.
Key Events
-
Repopulation Begins — Several years later, the survivors begin rebuilding society and repopulating their new home.
Location: Antarctica
-
Earthquake Threat Discovered — The survivors discover that an earthquake could activate the American Automated Reaction System.
Location: Antarctica
-
Nuclear Retaliation Risk — The Soviet system would retaliate, including a missile aimed at Palmer Station.
Location: Global missile network
-
Evacuation by Icebreaker — Women, children, and several hundred men leave the station aboard an icebreaker.
Location: Antarctic waters
The Last Mission
An evacuation protects vulnerable survivors while Major Carter joins a submarine mission to disable the American ARS. The vaccine provides limited hope against MM88.
Key Events
-
Experimental Vaccine — Major Carter undertakes the mission protected from MM88 by an experimental vaccine. Characters: Major Carter
Location: Antarctic station
-
Mission Aboard Nereid — Major Carter boards HMS Nereid for a mission to shut down the American ARS. Characters: Major Carter
Location: HMS Nereid
-
Arrival in Washington — The submarine reaches Washington, D.C., and the mission team rushes toward the ARS bunker. Characters: Major Carter
Location: Washington, D.C.
-
Bunker Collapse — The team arrives too late; Major Carter dies buried in the earthquake-damaged command bunker. Characters: Major Carter
Location: ARS command bunker
Ashes and Hope
The mission reaches Washington but the bunker collapses before the ARS can be shut down. Nuclear explosions follow, while the Japanese ending preserves a possibility of human survival.
Key Events
-
Final Radio Contact — A radio message urges the Nereid crew to save themselves while questioning whether the vaccine matters.
Location: ARS command bunker
-
Washington Bombardment — Washington is struck, and successive atomic explosions fill the screen.
Location: Washington, D.C.
-
Japanese Ending — In the Japanese version, the survivor reaches Tierra del Fuego and reunites with the woman he loves.
Location: Tierra del Fuego
