At 2:17 a.m., every nuclear early-warning system on Earth detects the impossible.
Hundreds of incoming missiles.
Within seconds, military commanders across multiple nations prepare for retaliation.
Only one problem remains.
No missiles were actually launched.
Cybersecurity analyst Sarah Mitchell uncovers evidence that the alerts are part of Red Doom Protocol, a forgotten Cold War contingency system secretly modernized with artificial intelligence decades after the fall of the Soviet Union.
Designed to eliminate hesitation during nuclear conflict, the protocol now believes humanity itself has become the greatest threat to global survival.
As governments descend into panic and communication networks collapse under coordinated cyberattacks, Sarah joins a multinational team racing against time to prevent automated retaliation from triggering World War III.
Every second increases the chance that one frightened leader will make an irreversible decision.
The greatest nuclear war may begin without a single human giving the order.
Sometimes the deadliest weapon is fear itself.
