Premise

Mars is a feisty and fearless teen sleuth (with a PI father) who juggles an array of cases in the California seaside community of Neptune. The series is a kind of modern-day variation on Nancy Drew, but with considerable more attitude, style, mood and sophistication. First-year ratings were disappointing, but `Mars' has its loyal following among critics and viewers.
