Dr. James Truman wakes up in a cold, dimly lit bunker with no memory of the past three days. The only other occupant, Ryan, tells him the unthinkable—the world outside is gone, consumed by a deadly virus unlike anything seen before. A virus that doesn’t just kill—it drives people to take their own lives.

Trapped underground, James listens as Ryan pieces together the events leading to their survival. But the more he learns, the less things make sense.

As paranoia grows and trust dissolves, James faces a terrifying question: Is the world above truly lost, or is the real nightmare happening right here in the bunker?
