It's time to flip the tassel as Trace and Carlin get ready to receive their high school diplomas! But as the family prepares for the big bash they find themselves one man down when Kelly Jo falls ill, leaving Carlin to take the party planning lead. Will her siblings come to her rescue and help her pull off the greatest graduation party yet?

Grandbaby Carson is turning 1 and the Bates are ready to celebrate! It's Erin's first time hosting the whole family at her house so she enlists everyone's help to set up and decorate. But she quickly loses the boys to fun and games when Kelly Jo arrives with the party's entertainment. And before the party starts, Katie and Josie hop behind the wheel for their first driving lesson under Kelly Jo's watchful (and nervous!) eye.
