The series unfolds in the imaginary town of Neptune, California, featuring Kristen Bell as the main character, Veronica. She is a student transitioning from high school to college, who also works as a private investigator under the guidance of her detective father. In every episode, Veronica tackles a unique case while simultaneously working on a more intricate mystery. The first two seasons each presented a mystery that spanned the entire season, beginning in the premiere and concluding in the finale. However, the third season adopted a new approach, concentrating on shorter mystery arcs that extended over several episodes.
