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.
A teenage boy with an addiction to thumbsucking throws his family and those around him into chaos when he attempts to break his habit.
