Emma is nine years old, a curious and imaginative little girl with a passion for unicorns, spaceships, and Christmas trees. She lives with her eccentric family: her mother Sara experiments with molecular cuisine, her witty grandmother Loredana always speaks her mind, and her father Leo, a strict mathematics teacher, struggles to understand Emma’s world of fantasy. Emma’s most trusted companion is Mojito, her lively imaginary friend who helps her escape reality. But when her parents’ marriage begins to fall apart, finding a balance between dreams and real life becomes harder than ever. Meanwhile, Bob, Leo’s childhood imaginary friend, suddenly reappears in a desperate attempt to reconnect with him before vanishing forever.
