Based on the YouTube video "Random Grandma Hit My Son, I Called Police (FV Hibachi Storytime)" by FGTeeV, a family is peacefully sitting at their table in a restaurant. That is when out of nowhere, an elderly woman smacks one of the children on his head from behind him.

A documentary film crew happens to be in the area and begins recording every bit of the incident; from the smack itself to the resulting trial.
