When Brenda meets a cute boy she decides to invite him to her party Saturday night. After getting permission to actually have the party, she then hears Sandra tell a story about how when she was young and wanted to get to know a boy better, she would ""mistakenly"" tell him the wrong day of the party.

Brenda tries the idea and invites Ken over for Friday night instead, hoping that when he gets there he will meet her parents and stay for dinner. But Mary and Lester decide to go out to eat and are not home when Ken arrives.

Brenda decides to let him come in anyway, just to have a drink, but then Calvin shows up to drop off chairs for the party. When she tells them they need to leave, Mary and Lester arrive home and the boys hide.

Mary and Lester eventually catch the boys in the house.

Calvin befriends a new kid named Ron who says that his money comes from his rich uncle. He buys Calvin a new pair of shoes and offers to take Calvin and Brenda to a Stevie Wonder Concert. Mary doesn't like the way Ron is ""trying to buy friends.""

For $50, Ron gets Calvin to give someone a sealed package and in return he receives $1000 to give back to Ron. Once Pearl and Mary find out, they conclude that Ron is a drug dealer. Mary goes to talk to Ron's mother about his free spending and the fact that he is a drug dealer, but his mother refuses to believe Mary.

Calvin confronts Ron about using him to deliver drugs and Ron admits that he used Calvin and all it cost him was a pair of shoes.

Later that day at a drug meeting, Ron's mother shows up and tells the 227 residents that Ron was stabbed to death in a drug deal gone bad.

For a choir sing-off, Mary has found housing for all of the competitors except one, and for good reason. He is rude, pushy and impatient. He winds up staying with the Jenkins.

He tries everything he can to guarantee that his choir will win, including taking the judges to dinner and bringing in a professional gospel singer.

The D.C. choir brings in Brenda, Tiffany and friends to sing with their choir, which gives them a unique, youthful sound. The competition ends in a tie, where both teams will represent the East Coast in the California semi-finals.
