Roc wants a management job with the Sanitation Department, but he's lacking one qualification, a high school diploma. When he learns that he can get his diploma by achieving a good grade on the GED Test, Roc prepares for the examination with the help of his family.

As Sheila is about to celebrate her twelfth birthday, Roc wonders why she refuses to visit her father, Calvin, in prison. Meanwhile, the Emerson's doctor offers to reveal the sex of their baby, which is due to be born at any time. Eleanor insists that she wants to be surprised during the birth, but Roc is impatient to know what kinds of baby clothes and toys he should scavenge from his garbage route.
