Soon questions arise: Is there really a fourth Houston sister? And what are the true identities of Tessa, their former housekeeper, and Aniyah Sanchez, a mysterious and seductive woman who shows up at the funeral? Worse still, the sisters are devastated to find out that Aniyah has inherited their home, the Houston Estate, and they must move out.
