Season finale. Roz plans a fancy gala on the Space Needle for ATLY’s 75th anniversary. Gil must cater to Catherine Williams, an eccentric old woman and the only surviving original radio personality.

One thing leads to another and the two of them share a surprise kiss under the moonlight. Roz struggles to keep everything in order after promising to keep the party quiet and sensible, but the real situation unfolds when Catherine is found dead in the gift shop.
