Adaptation of the award-winning comic series created by Frank Miller. Interweaving multiple storylines from the series' history, the film paints a picture of the ultimate town through the eyes of its roughest characters. There's the street thug Marv (Mickey Rourke), whose desperate quest to find the killer of a prostitute named Goldie (Jaime King) will lead him to the foulest edges of town. Inhabiting many of those areas is Dwight (Clive Owen), a photographer in league with the sordid ladies of Sin City, headed by Gail (Rosario Dawson), who opens up a mess of trouble after tangling with a corrupt cop by the name of Jackie Boy (Benicio Del Toro). Finally, there's Hartigan (Bruce Willis), an ex-cop with a heart problem who's hell-bent on protecting a stripper named Nancy (Jessica Alba).

Jessica Alba stars in this fourth film in the children's action adventure series. Teenage twins Rebecca (Rowan Blanchard) and Cecil (Mason Cook) have never got along with their stepmother Marissa (Alba) since she married their father, spy-hunting reporter Wilbur (Joel McHale). Unbeknown to the twins, however, Marissa is in fact a retired super-spy. When Earth comes under threat from the villainous Timekeeper (Jeremy Piven), Marissa is called back into action, and Rebecca and Cecil must put their resentments aside and assist her in protecting the future of the human race.
