Shanté Smith (Vivica A. Fox) is so adept at keeping her man happy and committed that her best girlfriends Diedre, Karen and Tracye (Mo'Nique, Wendy Raquel Robinson and Tamala Jones, respectively) depend on her for advice whenever "man trouble" clouds the horizon. But when Shanté's boyfriend, Keith (Morris Chestnut), is caught stepping out with her archrival (Gabrielle Union), Shanté resorts to her arsenal of weapons designed to bring a man to his knees . . . and back to her. Unfortunately, the happy ending Shanté expects goes sideways when Keith begins following the advice of his buddy Tony (Anthony Anderson). In this comedic battle of the sexes, Shanté's about to discover that not only are there no rules, she's not the only one playing.
