Laughter is a skill. Do you practice?
Promise was born laughing. Instead of crying when she was hungry, needed changing or a cuddle, she laughed. Growing up with her grandmother in a deserted by parents village, she practised her special skill every day by helping others find their laughter. When her parents return to take her back, away from her village, to another country, Promise has to find the origin of laughter in order to save the world, her world.
