More snakes reach the submarine than intended, leaving twenty venomous animals aboard. Andrea warns that their venom acts rapidly and that only two antivenom vials exist.
Key Events
-
Too Many Snakes Board — More than the intended animals reach the submarine during evacuation. Characters: Dr. Andrea Swanson
Location: Submarine
-
Twenty Snakes Confirmed — Twenty highly venomous snakes end up aboard the submarine. Characters: Dr. Andrea Swanson
Location: Submarine
-
Antivenom Shortage Revealed — Andrea warns that the venom can disable the nervous system within minutes. Characters: Dr. Andrea Swanson
Location: Submarine
-
Compartment Search Begins — The crew searches every compartment while trying to locate the snakes.
Location: Submarine compartments
-
Snakes Seek Warmth — The snakes move toward warm places inside the vessel.
Location: Submarine compartments
A Dangerous Coastal Escape
The crew searches the submarine while the snakes seek warmth. Nearby missile frigates force a risky course change into Chinese coastal waters.
Key Events
-
Snakes Seek Warmth — The snakes move toward warm places inside the vessel.
Location: Submarine compartments
-
Frigates Appear Nearby — Several missile frigates appear near the submarine.
Location: Open waters
-
Course Enters Chinese Waters — The submarine changes course into Chinese coastal waters to avoid confrontation.
Location: Chinese coastal waters
Torpedo Warning
A hostile submarine fires a warning torpedo, causing limited damage. Sonar signals possible retaliation, and the opposing submarine withdraws while the snake threat remains unresolved.
Key Events
-
Warning Torpedo Fires — A hostile submarine fires a torpedo as a warning rather than an attempt to destroy them.
Location: Chinese coastal waters
-
Submarine Survives Impact — The submarine survives the near impact and suffers limited damage.
Location: Chinese coastal waters
-
Sonar Signals Retaliation — The submarine activates sonar to suggest that it can retaliate.
Location: Chinese coastal waters
-
Hostile Submarine Withdraws — The opposing submarine withdraws, but the snakes remain a threat aboard.
Location: Chinese coastal waters
