The Perks of Being a Wallflower is based on the wildly popular novel by Stephen Chbosky about a freshman named Charlie who is always watching from the sidelines until a pair of charismatic seniors takes him under their wing. Beautiful, free-spirited Sam and her fearless stepbrother Patrick 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.
