In Sunray, a backwater town on Australia's Murray River, there's little to do but fish or listen to the local radio station. D.J. Ken Sherry arrives from the hustle of Brisbane to run the station; he's mid-40s, detached, thrice divorced, hatchet faced. But both sisters next door find him attractive: awkward Dimity, only 20, who works in a Chinese restaurant with few patrons, and perky Vicki-Ann, a hairdresser with a hope chest who invents a happy future with Sherry based on little but his arrival. First Dimity then Vicki-Ann spend the night with Ken, one concluding he's her boy friend, the other her fiance. Then Dimity begins to smell something fishy.
