Unto the Third and Fourth Generation

Tony Cawson, 75 and in the early stages of dementia, has a dreadful secret dating back to his youth of which his daughter Rebecca is ashamed and which she dreads her children will discover. But Rebecca, a conflicted individual in a failing marriage, also has secrets in her past which she wishes to keep from them, and from her husband. As Tony's dementia worsens, and as Rebecca's inner conflicts lead to irrational behaviour, incidents occur which result in the gradual revelation of these secrets, with consequences for the whole family. Have the sins of the parents been passed down unto the third and fourth generation?
