The diner gets some unexpected customers when Ralph orders a shipment of fresh fish that turn out to be more lively than anyone expected. Misty turns to Roland for help, but the vampire has his own worsening problems. His soul has an out-of-hell expiration date, and he needs Misty's help to find the cure before he sleeps with the fishes. Permanently.
Now it's a race against time and the Devil as Misty and Roland swim their way up the stream of questions to the lake of answers.
