You thought you'd seen it all last season, but ABC's "Dirty Sexy Money" gets a whole lot filthier, steamier, and more decadent in the show's second season. ET goes behind the scenes of the critically acclaimed show to find out all the lavish secrets and scandals of one NYC's most elite families, the Darlings.

Other than turning up the drama, "Dirty Sexy Money" is turning up the heat with sultry new cast member Lucy Liu, whose mysterious character Nola Lyons stirs thing up with the exorbitantly wealthy family.

This season also has more than a few plot twists and turns in store for viewers. The Darlings' reluctant lawyer, Nick George (Peter Krause), is thrust back into the dark side of excess, causing him another internal battle of morality. Patrick Darling's (William Baldwin)  marriage hits rock bottom as he searches for his transgendered mistress. And as if tensions weren't high enough, the whole Darling clan gets turned on its head when there is a death in the family -- and one of their own is under suspicion for the murder.

Apparently the Darlings aren't quite so darling after all. See what's really behind all the glitz and glamour on "Dirty Sexy Money," premiering Oct. 1 on ABC at 10 p.m.
