The Perks of Being a Wallflower is based on the wildly popular novel by Stephen Chbosky about a freshman named Charlie (Logan Lerman) who is always watching from the sidelines until two charismatic seniors take him under their wing. Beautiful, free-spirited Sam (Emma Watson) and her fearless stepbrother Patrick (Ezra Miller) shepherd Charlie through new friendships, first love, burgeoning sexuality, bacchanalian parties, midnight screenings of The Rocky Horror Picture Show and the quest for the perfect song.
