On a windswept cliff overlooking a bustling port city stands a small, shy lighthouse named Lumy. While the big city lighthouses boast powerful, far-reaching beams, Lumy's light is small and his voice is just a gentle hum. He feels insignificant until a terrible, thick fog rolls in, silencing the big lighthouses and trapping the ships. Lumy discovers that his unique, soft light and gentle hum are the only things that can pierce the fog. He must find the courage to sing his own small song to guide everyone home, learning that size doesn't measure the strength of one's light.
