When a routine speeding incident turns into a full-blown highway "situation," Madea (Tyler Perry) mouths off to a cop and lands herself in jail, where she's suddenly trapped behind bars with more motherly instinct than she knows what to do with. But Madea's nurturing side comes in handy when she crosses paths with a recovering drug addict turned prostitute (Keisha Knight Pulliam) who needs all the love she can get.
