A group of sisters ... hmm ... four of them I think. The parents are dead I think, and Gabrielle's character Eva is the eldest. They are all maybe 20 and above. Because Eva is the eldest she is very protective and ruthless, with a sharp tongue.
The spouses of the other sisters feel overwhelmed by Eva's control over their wives lives, and thus their own that they become desperate. They pay a friend (LL Cool J) to romance Eva to get her out of their hair. And romance ensues between the two.
