The squad heads to the mountains, but something strange in the sky disrupts their fun.

Since the Jersey Shore squad started taking family vacations, there have been 14 trips and a lifetime of memories. But throughout their adventures, they have always felt like something was missing. Now that’s all about to change with one sweet return.

Just an ordinary day at the lake, filled with boating, drinking, fighting, lap dancing…and a revelation that leaves the roomies speechless.

Mike continues his battle with Angelina over their Twitter war, meanwhile Pauly and Vinny hatch a plan to give Mike the gender reveal of his dreams: 10,000 ft in the air. The only problem is making sure Lauren doesn’t find out before he jumps.

Sammi's making up for lost time, catching up with her old roomies, and figuring out the new dynamics of the group; there's still a lot of unsettled business between Angelina, Deena, Jenni, and Nicole.

On the eve of the Dancing with the Stars premiere, Pauly and Mike travel to LA to support Vinny. Meanwhile, a girls’ weekend in wine country goes off the rails when Meatball Merlot meets a Danish beer festival.

The roommates are shocked when Vinny’s birthday party unexpectedly turns into Angelina’s engagement party. But what’s even more unexpected is what happens after Angelina says yes.

Mike wants to win it all, Prickly Elder wants to go to bed, Snooki wants to start a fire, and Angelina wants Vinny. But what does Vinny want?

Vinny invites Angelina to his apartment… is it a date? Nicole invites the girls to California for a business trip/wild weekend in wine country, and the Keto Guido is invited to dance with the stars.

Vinny and Angelina get spicy; the Meatballs embrace their wild side; tensions get so hot one roommate leaves to cool off; the party continues tonight with part two of the reunion.

What's next for Angelina after revealing her true feelings for Vinny? And, in the words of Pauly D, a game of truth or dare gets “Awkward." Plus, the cornhole finals are here and The Situation is ready for Jay Cutler.

Vinny dances, Mike makes some questionable fashion choices, and the upcoming family vacation to New Orleans is about to be taken over by beef between Angelina and Mike.

Angelina’s new man arrives just in time for her divorce party. Snooki burns Ang’s wedding dress. Pauly takes everyone to the hauntedest house ever. And Deena makes it clear she’s not afraid of JWOWW.

Deena’s jazz night with costumes is only outdone when she plans another Family Fun Day with matching shirts. Plus, Angelina invites her new boyfriend on vacation, but will her Twitter beef with Mike ruin her man’s introduction to the family?
