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.

While the other housewives recover from Joan's dock blow-out, Kara frets over the details of her upcoming dinner party. But with an amazing chef, cheese flown in from Italy and specially inscribed gifts for her guests what could possibly go wrong?

The ladies throw Roxy a surprise birthday party to make up for the botched celebrations in Muskoka, but the biggest surprise comes when Kara shares the news of a recent injury, and Joan receives a hostess gift filled to the brim with meaning.

Roxy is shocked by some gossip her Lash Girl shares with her and doesn’t know what to do with the information. Meanwhile, Ann has a surprising proposal for her husband Stephen and Kara makes a charitable pitch to the other wives.

Jana and Grego are reeling from the gossip Roxy shared with them and decide to take the bull by the horns, but doing so unexpectedly leads to Joan confronting Roxy at Jana’s charity event.

The housewives enjoy a whirlwind trip to beautiful Barcelona, but return to Toronto to discover many unresolved issues await them.

Joan and Kara finally confront one another at a shocking lunch. Kara further escalates the emotions when she shows up at Pierre’s birthday party.

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 war.
