Ten young Hampton locals gear up for the most exciting summer of their lives. But everything changes when a newcomer arrives from the city to shake things up and they realize that their Hamptons bubble is about to burst.

It’s Fourth of July in the Hamptons and the crew gets together at Ilan’s for a party. Drama ensues as Hunter confronts Ilan, Reid tries to clear the air with Milo, and a chicken fight reveals someone’s true colors.

The morning after Ilan’s party brings more than just trash to clean up. Frankie tries to make things right with Reid and Milo, while Juliet and Habs use the situation to discuss their similar experiences growing up in the Hamptons. And as Ilan juggles two dates in one week, Avery works on building new friendships, and Emelye finds solace in the ones she already has.

Reid throws a party to try and bring people together, only to have everything fall apart. An Instagram post reveals to Emelye just how much she’s being excluded, Habs goes on a date with an old friend, and Ilan learns that sometimes honesty is the best policy.

Lottie throws a boat party, and the common denominator of the summer drama becomes clear. Meanwhile, Emelye’s sister questions the validity of her life goals, and Avery tests the waters of her relationship with Frankie. A new Dockers employee joins the team, and Ilan’s mom gives him advice, but mother can’t always be right.

Emelye plans to throw a White Party but Hunter might RSVP “no” once he finds out who’s invited. Sophia keeps Ilan in the friendzone, while someone else’s ex may cause a budding relationship to wilt. And after Reid apologizes to Avery, will it be enough to fix their fractured friendship? Or will Avery be heading back to school with one less friend than before?

Avery hosts a black tie event, and Lottie's boyfriend causes things to get heated. A first kiss takes Ilan’s relationship to a new level, while Juliet struggles with her family’s rejection of her boyfriend, Tony. Frankie wonders whether he’s going to be part of Avery's post-summer plans.
