With the royal wedding about to take place, Mister Rogers arrives with figures of King Friday and Sara Saturday for the top of the wedding cake. He sings I'm Going to Marry Mom before Miss Emilie stops by dressed beautifully for the big day. She takes a moment to share a poem about the royal couple before departing for the wedding. As she is leaving, Chef Brockett arrives and with the wedding cake which "took 81 hours" to make. After placing the figures of the King and his bride on the cake, Chef Brockett leaves for the castle while Mister Rogers takes a pretend bath and puts on his pretend purple gloves. In the Neighborhood of Make-Believe, Edgar Cooke is helping King Friday put the final touches on his hair. Lady Aberlin arrives with the Queen's new crown. She is surprised to learn that King Friday wants the wedding to be held in the castle garden when the plans have already been made to have it in the W room. With only 4 1/2 minutes to move the festivities, Lady Aberlin and Edgar Cooke scurry off to make the necessary changes and are promptly joined by Chef Brockett. X the Owl gathers the others who all come to the garden for the wedding. Mr. Anybody, set to serve as the official for the service, is having trouble locating the castle until Lady Aberlin finds him and shows him the way. Finally, the ceremony is underway with the crowning of the new queen. The wedding begins. Miss Emilie reads the royal poem before King Friday and Queen Sara take center stage. Following the ceremony, everyone adjourns to the C room to enjoy Chef Brockett's cake. Back at the house, Mister Rogers reflects on the fun that was had at the wedding and suggests that after the excitement of a wedding, people often like to have some peace at quiet. He concludes by singing Peace and Quiet. Part of the "Mister Rogers' Neighborhood" series.
