Bad girls club centers on 18 mischievous and rebellious women with different backgrounds and personalities, who have a number of psychological and behavioral problems. They are introduced to change their pernicious behavior and accomplish specific goals. The cast, deemed "bad girls", enjoy a luxurious lifestyle in a fine mansion for one year, during which they must obey specified rules.  If a "bad girl" breaks a rule, she is evicted from the show and, if it is early in the season, replaced by a new "bad girl".
