Watch Shirtless Zac Efron, Seth Rogen in Raunchy Neighbors 2 Trailer

The highest-grossing live-action film of Seth Rogens career, 2014sNeighbors introduced audiences to Mac (Rogen) and Kelly Radner (Rose Byrne), first-time parents who wentto war whenTeddy Sanders (Zac Efron) and the rest of hiswild fraternitymoved in to the house next door. Now, Universal has just dropped the first trailer for the comedys sequel, this summers Neighbors 2: Sorority Rising.

Picking up where the original left off, Sorority Rising flips the script by proving that Greek life doesnt discriminate when it comes to disturbing the peace. When frustrated undergrad Shelby (series newcomer Chlo Grace Moretz) decides to start a party-hard sisterhood, she and her two best friends move in to the house next to the Radners has been recently abandoned. Maybe it wont be that bad! Mac tells his unamused wife. Girls are usually quiet, they dont take hard drugs, and theyre much smarter.

Cue binge-drinking, clumsy pole-dancing, a passed-out sorority sister in the back of Rogens car (who finds time to flip him the bird before flying out his front windshield), and the kind of hedonistic chaos that makes Spring Breakers look like Sesame Street. We need someone who can relate to stupid young people, Rogens character says. And so he turns to Teddy, his former nemesis, for help in purging his neighborhood of the greatest threat its ever known.

Ike Barinholtz and Dave Franco are among the supporting actors who are set to reprise their roles, while new members of the cast includepop star Selena Gomez and street comedian Billy Eichner. Neighbors 2: Sorority Rising opens on May 20th.
