Madness spread world-wide and there's no stopping it. If you're symptomatic, you may go mad next! Their cruise ship, Intrepid is running on fumes. There's only one place they can reach with the fuel they need. But the costs maybe too high.
And they better hurry, because when they run out, they'll have no way to control the parasitics onboard, who are desperately driven to kill.

The captain has a plan, and it will shock everyone.
