Plot summary: A US naval warship is secretly being tested for deployment which is actually a ruse to prevent the crew from finding out about the true nature of their mission. They’re carrying two secretive Centers for Disease Control and Prevention scientists who are working on a cure for an airborne virus that had only affected a handful of African villages, but after four months at sea it’s wiped out 80% of the world’s population including the United States government. It has a 0% survival rate and is highly contagious. All governments have ceased to be and the crew of the warship are on their own.
Kinda makes you think of the Ebola crisis, doesn’t it?
And World War Z.
