A demented old man's memories are buried deep like stones in water. He throws stones into a lake and each stone recalls the surface happiness in his life, shared with his two daughters when they were children. Now fully grown up, his eldest daughter, Rebecca, takes him to school only for the old man to have a strange episode - he mistakes his grandson's friend for his youngest daughter, Jennifer. Later that night, Rebecca recalls this episode at dinner, only to get a stinging rebuke from her husband. We later find out that, in fact, Jennifer led a very troubled life, unlike the old man's memories. Finally, only an unexpected family tragedy has the force to shatter the placid surface and reveal the truth behind the old man's hidden memories.
