*Winner Kids Jury Award 2022* 10-year-old Lucy is simply too good for this world. She dutifully helps out in her parents' ice cream parlour and puts a smile on every customer's face with her dad Pietro's delicious ice cream creations. But then disaster threatens: The expensive ice cream machine breaks down and the parlour is on the verge of closing. Where is the money for the repair going to come from so quickly? After pondering for a long time, the otherwise amiable Lucy sees only one way out. In order to prepare for her top-secret mission, she puts "Operation Lucyfer" into action and takes lessons in being a gangster from the class rogue Tristan. Will it end well?
