Blue Is The Warmest Color centers on a 15-year-old girl named Adèle who is approaching adulthood and dreams of experiencing her first love. A handsome male classmate falls hard for her, but an unsettling erotic reverie upsets the romance before it begins.
Adèle imagines that the mysterious, blue-haired girl she encountered in the street slips into her bed and possesses her with overwhelming pleasure. That blue-haired girl is a confident older art student named Emma, who will soon enter Adèle's life for real, making way for an intense and complicated love story that spans a decade and is touchingly universal in its depiction.
