Femme Fatales is a show that can best be described by its timeslot and channel -- "After Hours on Cinemax".

Anyways, it's usually psychological thriller type plots usually, but there is an episode coming up next season (already filmed) that involves a vigilante superheroine named Libra. Here is an interview with the star playing her, Betsy Rue:
