Rosa is a little flower fairy who always lived alone in her rosebush. More than anything she dreams of having a friend, but she is too scared to ever leave her bush. One day the adventurous butterfly Silk crosses paths with Rosa and they immediately become friends despite their differences. Silk wants to go on adventures and Rosa wants to stay in her rosebush. But when Silk is kidnapped by an evil Stone Troll, Rosa has to let go of her fears and set out on a dangerous journey to save Silk.
»As a child, my dad read aloud from the “Rosa” books, and the amazing universe has followed me ever since. I still today want to live in the Summerland with Rosa and her friends, sleep in the rose bush, eat blueberry pie with the mice and dance with the elves that twinkle like silver in the night. With "Rosa and the Stone Troll", I want to create an adventurous film about friendship. About how we each try to fit into the community based on our individual prerequisites and challenges. And about how, in our fear for loneliness, we will do everything to fit into the community.« (Karla Nor Holmbäck)
