Thumbsucker

Justin (Lou Taylor Pucci) is a teenager boy, who
has an oral obsession with his thumb. His mother
(Tilda Swinton) seems to be a normal housekeeper,
but she has her own obsessions as well, like a
crush on a TV-star (Benjamin Bratt). The only
person who's aware of Justin's problem is his
father (Vincent D'Onofrio), manager in a store,
but none of his advices seem to be working for
Justin. The kid is signed up in a debate workshop,
but the thing isn't going well, because he has his
mind in a pretty classmate and, of course, in his
thumb, affecting all the rest of his classes. So,
Justin is a loner kid in the school, who prefers
to lock himself in the bathroom and suck his
thumb. Justin's dentist (Keanu Reeves), a
mystical-hippie person, will try to help to
overcome his thumb problem, through the hypnosis.
But the school's psychologist will diagnose Justin
with the Attention Deficit Disorder, and will
prescribe him some drugs. Suddenly, Justin's
problem with his thumb will disappear, becoming an
hyperactive genius, winning several debate
contests and the admiration from his teacher
(Vince Vaughn). Nevertheless, more serious
problems will come for Justin with his mother, his
father and with a drug addiction.
