When last we saw Mac and Kelly Radner (Seth Rogen and Rose Byrne) things were finally starting to calm down for them and their newborn daughter. But calm doesn’t make good material for a sequel, and so for the upcoming Neighbors 2 (subtitled Sorority Rising, apparently), things are about to get rowdy again. At least according to Wikipedia’s plot synopsis. And Wikipedia is never wrong:

Mac and Kelly Radner reunite with Teddy and Pete to help battle the sorority sisters who move in to their neighboring house.

Teddy is Zac Efron; Pete is Dave Franco, and they team up with their old arch-rivals from 2014’s comedy smash to do battle with a new sorority, which includes Chloë Grace Moretz. Also back for the sequel is director Nicholas Stoller and Zac Efron’s chiseled abs.

New for this installment, according to one of three new pictures released online, Seth Rogen’s chiseled abs (or magic-markered abs, whatever):

And here’s one more new picture for you, confirming the peace accord between the Radners and Delta Psi Beta.

And hey, there’s even a new poster too, complete with underwear humor.

The first Neighbors was such a great take on a simple idea, you hope they don’t sully the memory of the original with this sequel, the way so many comic follow-ups do. At least they’ve got the same cast and creators in place, and tossing a sorority into the mix is a pretty solid premise for another go-around (thankfully, they didn’t start another prank war between the same characters). And given how women are typically portrayed in gross-out comedies (although not, it should be noted, in the first Neighbors, thanks to the wonderful Rose Byrne), it’ll be an interesting switch to see them acting rowdy and having fun. It’s about time.

Neighbors 2: Sorority Rising (aka #Neighbors2) opens in theaters on May 20.
