As loud parties continuously disrupt the peace, the couple turn to former neighbor and onetime enemy Teddy Sanders (Zac Efron) for help. Now united with the fraternity stud, the trio devises schemes to get the wild sorority off the block. Unfortunately, the rebellious young women refuse to go down without a fight.
