Jess crashes a funeral, hoping to delete a “sext” she recently sent to the deceased. Then, Schmidt’s mom, Louise, arrives in town for a visit to demand he write thank-you notes for his bar mitzvah gifts, and Winston is desperate to be off-duty friends with his police partner, Aly.

When Cece and Schmidt ask Jess and Nick to be their Maid of Honor and Best Man, respectively, their first task is to plan the engagement party. But when Jess invites Cece's mom to join in the celebration, Cece is forced to make a surprising announcement to Schmidt.

Things heat up between Nick and Reagan over who can provide the loft with the best air conditioning unit. Meanwhile, Winston uses his “cop voice” to help Schmidt prep Cece for a newscaster audition.

Refusing to accept that their crazy days are behind them, Jess and Cece abandon their low-key bachelorette party plans and seek a night out to top all others.

Schmidt makes a last ditch effort to convince Cece's mom to come to their wedding, but in doing so, he might miss the special day himself.

While the gang helps Schmidt & Cece remodel their fixer-upper, Jess spearheads a vote to let Reagan eventually move back into the loft. Meanwhile, Nick and Winston make a revealing discovery and Schmidt and Cece learn the art of compromise.

Jess avoids her feelings for Nick by taking care of her dad in Portland. While attending a work party with Reagan, Nick panics that they really don't know each other. Meanwhile, Aly prepares to meet Winston's mom for the first time, as Winston admits he hasn't told her they are cops.

Jess is ready to tell Nick of her true feelings for him. Meanwhile, Nick takes a meeting with a book publisher, as Aly helps Winston reconnect with an important person. Then, Cece and Schmidt receive big news.

Jess and Nick come back from a book tour for "The Pepperwood Chronicles" across Europe.

The gang takes a tour down memory lane, which includes a final round of "True American."
