The story takes place in the office of Dr. Harper, a psychiatrist, where a man named Lester Billings talks to the doctor about the "murders" of his three young children, describing the events of the past several years.
Approximately a year after their second child's death, Lester's wife, Rita, became pregnant with their son Andy and subsequently moved to a different neighborhood, far from the old one.
Feeling the malevolent presence growing bolder in his wife's absence, Lester began to panic and decided to move Andy to a separate bedroom, knowing that the monster would go for him.
He later returned home at dawn, called the police, and discovered Andy's corpse on the floor with the closet door ajar.
