Kelly and Mac are settling down in a quiet neighborhood with their newborn child, until the frat brothers move into the house next door. Teddy is the President, and Pete is his right hand man, and they’re quick to accept friendship when Kelly and Mac introduce themselves as the neighbors. Night after night, Mac asks Teddy to lower the fraternity’s noise, even accepting the invitation to the party one evening.
