A woman has to learn how to love and trust men all over again in this comedy drama. Helen McCarter (Kimberly Elise) would seem to have it all -- she's been married for 18 years to Charles (Steve Harris), and over the course of their time together, he's become one of Atlanta's most successful attorneys. But despite wealth and prestige, things are not as they should be at the McCarter home, and on their anniversary, Charles drops a bombshell on Helen -- he's divorcing her for another woman. Escorted out of the house with nowhere to go, Helen moves in with her grandmother Madea (Tyler Perry), a sassy woman with no shortage of opinions and a gun that she's not afraid to use. As Madea helps Helen get back on her feet emotionally, the divorcée makes the acquaintance of Orlando (Shemar Moore), a handsome man who is obviously attracted to her. But after her experiences with Charles, Helen isn't sure if she's ready to trust a man again. Diary of a Mad Black Woman was adapted from the popular stage play by Tyler Perry, who also plays several roles in the film, most prominently Madea; it marked the first feature-film credit for successful music video director Darren R. Grant.
