Nina Sayers (Portman) is an extremely dedicated dancer to dance, much because of her mother's demands, who controls her career. When she gets the chance to be the protagonist of an adaptation of Swan Lake, Nina wants to shine to the fullest. However, the arrival of Lily (Kunis), a ballerina not as dedicated as she, to the artistic body radically transforms Nina's behavior. Approved with 85% at Rotten Tomatoes (seal "Fresh"), the feature still received the Oscar for best actress for Natalie Portman.
