Katherine works on an isolated farm run by Hester and Hester's father Francis. Unhappy because of her heavy workload, Katherine wants to leave. Hester doesn't want her to go, because she is attracted to her younger friend. She manages to convince Katherine to stay by promising to give her less work in the future. When old Francis dies, Hester sells the farm for cash, and she and Katherine move to a small cottage on the farm's edge, from where they plan a trip to Europe. A tragic accident and the theft of their money changes their plans.
'Miss Hester Harper, middle-aged and eccentric, brings Katherine into her emotionally impoverished life. Together they sew, cook gourmet dishes for two, run the farm, make music and throw dirty dishes down the well. One night, driving along the deserted track that leads to the farm, they run into a mysterious creature. They heave the body from the roo bar and dump it into the farm's deep well. But the voice of the injured intruder will not be stilled and, most disturbing of all, the closer Katherine is drawn to the edge of the well, the farther away she gets from Hester.'
