Ten-year-old detective Agathe-Christine dreams of being a private detective. With her own private office, AC - as she prefers to be called - is always in search of the next mystery to solve. When she moves next door to a puzzling skater, Vincent, AC immediately gets the sense that there's more to him than his relaxed, loner vibe lets on. She decides to drop all of her other leads in pursuit of surveilling Vincent full time, but what she discovers may be more than what even she expected. Next Door Spy challenges archetypical characters as each protagonist is forced to look beyond the surface to reveal the unique self that lies within. In Danish with English Subtitles.
