In this twisted tale, JOAN HACKETT and SCOTT JACOBY are mother and son, who have created a world unto themselves.  They share each others thoughts and the 10 year-old boy has taken the role of 'the man of the house'.  Into their lives comes the eccentric younger man ROBERT KLEIN.  He and the mother start dating, despite their difference in age, and then they marry, much to the horror of the boy.  Once they return from their honeymoon, the boy requires so much attention that the new father deserts the family!  However, he comes back and reconciles, so the boy then devises a plan to get his mother back, and to get rid of the new father....permanently!
