Sam, an owl, awakens one night and looks for a playmate. However, since it is the middle of the night, all the creatures are asleep. Sam then comes across a series of flying lights, one of which hits Sam in the head. It is Gus, a firefly. Gus shows Sam the trick he can do, which is that he can make glowing lines in midair using his light. Sam is amazed and decides to have fun by having Gus follow him directly as he flies. Sam flies in the shape of various words; Gus thinks this is fun and decides to do more on his own. However, he has mischief on his mind.
