In the next episode of "Black-ish," Grandma Ruby (Jenifer Lewis) offers to chaperone Junior Johnson (Marcus Scribner) and his twin siblings Jack (Miles Brown) and Diane (Marsai Martin) after he fails at his driving test.

The synopsis and promotional photos for the upcoming installment titled "Charity Case" was just released recently and showed Ruby accompanying Junior, Jack, and Diane on a trip which turns out to be an informative outing. Apparently, Junior just flunked his driving test which prompts Ruby to go along with them. She allows the eldest kid to drive but it appears that she is a bit concerned about his skills. Jack and Diane follow along and do not seem to be as worried as their grandma. They enter an establishment and park the car outside for a while. However, once they return, they notice that the rear left tire of the car has been locked.

Ruby appears shocked and looks angrily at Junior. It seems he may have forgotten about the time limit of the parking slot. It looks like they have to figure out a way to get out of that mess. Meanwhile, Junior's dad Andre (Anthony Anderson) gets chosen to lead a new charity campaign to give back to their community. Nevertheless, his wife Rainbow (Tracee Ellis Ross) tells him that there is more to giving back than writing checks. Andre decides to donate some of his clothes to a man in need.

In the last episode, Andre and Rainbow received word that a relative was going to be released from prison. Andre wanted to let the ex-convict stay at their house but his wife convinced him not to in order to protect the kids from anything that could happen.

"Black-ish" season 4 episode 8 will hit the airwaves on Tuesday, Dec. 5 at 10 p.m. EST on ABC.
