With Ann's wedding vow renewal fast approaching, Roxy and Jana plan a risqué stagette, but Ann is finding it hard to hear her wedding bells with all the fighting among the wives. She gathers everybody together for a “Peace Lunch” to clear the air only to find that some ladies are ready for a fight.
While the other housewives recover from Joan's dock blow-out, Kara frets over the details of her upcoming dinner party. But even with an amazing chef, cheese flown in from Italy and specially inscribed gifts for her guests, not everything goes as planned.
All the women pack their bags to head to their luxurious lakeside Muskoka retreats and attend Joan's infamous Dock Party. Everyone wonders if the rumors of debauchery, skinny-dipping and tension with Roxy ultimately scare Kara off.
