Two strangers, Gwen and Simon, find themselves stranded in a roadhouse on the bend of a nameless highway. Neither can really recall how they got there, or knows where they're even at. More troubling is the strange feeling that they shouldn't even be concerned, but when they make a horrifying discovery, all that changes. With no more than the hand-drawn map tucked inside a lurid pulp novel to guide them, they make a desperate flight down the highway. Dogged by hazy recollections, and their own twisted dreams, they're pursued by an other-worldly black dog and a cryptic old man on a bicycle who always seems one step ahead of them. They're uncertain where they're head, and even less prepared for the truth that awaits them.
