The Well (1998)

Spinsterish Hester Harper hires young Katherine as help with her elderly father on her farm in the Australian Outback. A friendship soon grows between the prim, repressed Hester and the young, carefree Katherine, with Hester lavishing gifts upon Katherine. After Hester’s father dies, Katherine persuades her to sell most of the farm off. They start to spend up with reckless abandon, so carelessly that they simply keep the money from the sale of the land in old biscuit tins. While on their way back from a party, they run someone down on the road. With Katherine in hysterics, Hester throws the body down the well. They then find the dead person is a thief who robbed the house and that Hester has thrown all the money down the well with him. Katherine starts to go to pieces, insisting that the dead man down the well loves her and that he is going to come after Hester if she tries to stop them.
