John Grant, a young Englishman, teaches in Tiboonda, a tiny railway junction on the far western plains of New South Wales. He sets off to spend his summer vacation in Sydney but doesn't make it beyond Bundanyabba, a nearby mining town known as 'the Yabba'. Stranded in town after losing all his money in a two-up game, he finds himself engulfed by the Yabba's claustrophobic, nightmarish, beer-fuelled stupor, an atmosphere compounded of repressed sexuality, squalid violence, and the sinister mateship of the locals. After being sexually assaulted by the town's alcoholic doctor, he attempts to hitchhike out of the town but is brought back by a truckie. In anger, he tries to shoot the doctor but ends up only shooting himself. After discharging himself from the hospital, Grant takes the train back to Tiboonda, resigned to another year of teaching.
