Now that Mac (Rogen) and Kelly Radner (Byrne) have a second baby on the way, they are ready to make the final move into adulthood: the suburbs. But just as they thought they'd reclaimed the neighborhood and were safe to sell, they learn that the new occupants next door are a sorority even more out of control than Teddy (Efron) and his brothers ever dreamed of being.
