Inscription$ millionnaire$: L.A.

Josh Flagg and Madison Hildebrand return for a volatile fourth season joined by a new Josh: Josh Altman, who brings east coast flair to the west coast.

Josh F. deals with a client in denial, Josh A. risks his commission as a favor to his mother, and Madison jumps through hoops for a hard-nosed millionaire.

Madison gets bullied by a client, then Josh A. questions his pricing. Meanwhile, Josh F. takes his grandmother's advice to hire an assistant...or two.

A new client hires Josh F. to find a hip venue for a West Hollywood gay bar. Then, Madison gets mad to learn of Josh A.'s date with his assistant Heather.

When a billionaire client hits town, Josh A. has 48 hours to find a lavish estate. But he does find time to encourage Madison's assistant Heather to quit.

Madison must lease the high-end beach home of a tenant with six dogs, which makes showing the place a potential disaster and an angry seller challenges Josh Flagg's marketing strategy. Meanwhile, Josh Altman struggles to sell nine high-end lofts in Venice Beach and sparks fly when Madison accuses Josh Altman of trying to undermine his business.

When Madison gets in Josh A.'s face over territorial rites, Josh A. encourages Heather to walk. Meantime, Josh F. worries if his new book is too personal.

Josh A. will stop at nothing to list the house of his dreams - a Hollywood bachelor's den - then accuses Josh F. of ratting out Heather.
