On a warm summer night at Yankee Stadium, a terrifying plot to bring humanity to the brink of extinction is set into motion.
And as the deadly Medusa virus sweeps the globe unchecked, three survivors – an obstetrician dealing with the death of an expectant mother, a football star past his prime, and a soldier harboring a terrible secret about her own future – struggle to save what they hold most dear in a world crumbling around them.
Civilization is but a memory, and this is the dismal world left behind.
Spurred by the revelation that his daughter may have survived the Medusa plague, Dr. Adam Fisher treks across a ruined American landscape to find her. Along the way, he joins forces with Captain Sarah Wells, a soldier haunted by her immunity to the virus, and Freddie Briggs, a football star grieving the loss of his family.
As they make their way across a dead continent, the challenges mount around them, including the terrifying prospect that the Medusa virus may not yet be done with the survivors.
