Friends since birth, tomboy Kim (Tuva Jagell), mousey Bella (Wilma Holmén), and creative Momo (Louise Nyvall) have also been outcasts, perceived as lesbians, and bullied by their piers to the indifference of the teaching staff who tell them to toughen up. While Bella and Momo can only ponder why everyone hates them, Kim confesses to Momo that she feels as if she is a boy born in the wrong body. Having an interest in gardening nurtured by Bella's late mother, the three discover a strange root and plant it to see what it grows. Miraculously, the plant sprouts overnight a large black flower with vanilla-scented buds that seems to be attended by a swarm of black butterflies. The three drink the nectar seeping from the flower buds on a dare and find themselves magically transformed into boys. Finding acceptance among their schoolmates (who do not recognize them) as boys, the trio are galvanized to stand up for themselves in school when they transform back. While Momo and Bella are reticent to try the nectar again, Kim feels the need to find out if she really is a boy, and if there is something more to her newfound bond with skater Tony (Mandus Berg) who she also believes is "trying to be something he's not." On the cusp of womanhood, Kim is forced to choose between her friends and her search for her true self with results that are devastating but not world-ending. Based on the novel "Pojkarna (The Boys)" by Jessica Schiefauer, GIRLS LOST is a coming of age story with a touch of magical realism that is compelling, imaginative, and observant about the ways in which gender is socially constructed in youth.
