Jess applies for a job at a progressive new school, but things take a turn when she finds out the principal (guest star Lucy Punch) is dating her ex-boyfriend, Sam (guest star David Walton). Meanwhile, Nick gets a cold and Schmidt quarantines the roommates to prevent himself from getting sick before his big presentation.

Jess invents a male alter ego, "Jeff Day" in order to buy a new car from a sexist salesman, but her plan backfires when both Nick and Sam arrive at the dealership pretending to be him. Meanwhile, Schmidt and Cece panic when Winston decides to bring his new prankster girlfriend, Rhonda as his plus one to their wedding.
