Synopsis

Della, a wealthy, intelligent woman, arrives in the isolated family cottage, planning to spend the summer with her husband, their son and daughter. As the family gathers that first day, it appears that the relationship between Della, her children and her husband seem odd, to say the least. She seems to have difficulty relating to, what appears to be, rather unorthodox behavior on their part. The suspicion arises...is there a plot to drive Della insane, or is she just overcome by what appears to be rampant immorality?
