One night, Bubby's father Harold returns, having abandoned Florence years earlier to pursue a career as a preacher. Harold did not know he had a son, but he quickly comes to disdain Bubby, and mocks him for his presumed mental disorder. Harold beats Bubby, and encourages Florence to do so as well. Tired of the abuse, Bubby suffocates his parents with clingwrap, and decides to venture outside for the first time.
