Zyzzyx Road ( ), also called Zyzzyx Rd., is a 2006 American thriller film written, produced and directed by John Penney and starring Katherine Heigl, Leo Grillo, and Tom Sizemore.

Plot

Grant, a philandering accountant, goes to Las Vegas on a business trip and encounters a seductress, Marissa, and her jealous ex-boyfriend Joey. Joey attacks them and Grant and Marissa incapacitate Joey. Believing they have killed him, they decide to bury him along the eponymous Zyzzyx Road, a rural road off Interstate 15 in California's Mojave Desert (though there is a slight spelling difference between the actual Zzyzx Road and the road in the movie). We see Grant has a bump on his head and is hallucinating. After digging a grave, Grant and Marissa return to find Joey missing from the trunk of Grant's car. Grant chases Joey through the desert with a shovel, and when he finds him hidden in an abandoned mine, Joey tells Grant he wasn't trying to kill Grant, he was trying to kill Marissa because she's actually a succubus. However, that is revealed to be a hallucination as well.
