In the aftermath of World War II, the Earth’s population was devastated by a terrifying alien virus. Those who survived were changed fir ever. Some, known as jokers, were cursed with bizarre mental and physics, deformities, others, granted superhuman abilities, are known as aces.

In this volatile and divided world, intrigue and violence are never far away and a trip up the Mississippi River abroad the steamer Natchez is no exception. Boars filled with joker refugees spark conflict between super powered aces. Zombies and vast alligators lurk beneath the water. In the stream of the engine room, a spirit stands ready to defend its river boat home.
