A couple of Australians introduce three American backpackers to the local legend of Lemon Tree Passage where a ghost of a motorcyclist warns young drivers to slow down. After seeing the ghost first hand they uncover a malevolent force that posses the area and threatens to wreak havoc on the final days of their vacation. Isolated and ten thousand miles from home, the tourists find themselves caught in the clutches of an evil force much more heinous than the local myth believed. Written by David Campbell
