A teenage boy with an addiction to thumbsucking throws his family and those around him into chaos when he attempts to break his habit.
Dubbed the King Kong of oral obsessives by his hippie dentist, Justin Cobb is a 16-year-old desperate to find a way to break this embarrassing habit he has retained since infancy. His father, a former football star, tries to help by providing an antidotal cayenne-pepper cream and a healthy dose of fly-fishing. His mother, who works as a nurse helping the rich and famous sober up, seems more concerned with a fantasy romantic relationship with TV-star Don Johnson than with her son's problems. Hypnosis seems to work, but the problem surfaces in other forms from drug addiction to alcoholism.
