Strangers in the dark is an experimental film showing how light pollution makes a glow-worm's love life a living hell. Combining different techniques from animation to archive material the film follows glow worm's attempts to find a partner in an environment that is no longer dark at night. The story about light and darkness moves from the scale of planetary to microscopic, from the calmness of nature to a hectic city and from artificial light to the green shimmer of glow-worm's behind.
