Two years after feuding with a rowdy frat that moved next door to them, young parents Mac (Seth Rogen) and Kelly (Rose Byrne) are about to have their second child and move to a new house. Unfortunately, their attempts to sell their current home hit a snag when a sorority led by a rebellious college student (Chloë Grace Moretz) become their new neighbors. Desperate to get rid of the hard-partying gals, the couple forge an alliance with Teddy (Zac Efron), the former fratboy who tormented them the last time around. Directed by Nicholas Stoller.
