Jess is ready to paint the town purple when a chance encounter finds her and best friend Cece invited to a once-in-a-lifetime mansion party thrown by music legend Prince. Not wanting to miss out on the fun, Nick, Schmidt, Winston and Coach are determined to crash the festivities, building toward an Unforgettable ending.

Nick struggles to throw Jess the perfect birthday party, while Schmidt works overtime to help out Cece in her new job as bartender and Winston and Coach engage in a bake-off.

Jess tries to become good friends with Coach by watching Detroit Pistons games with him and becoming a Pistons “fan”. However Jess’ “fandom” starts to interfere with her relationship with Nick, who is a lifelong Chicago Bulls fan. Winston agrees to shadow Schmidt at his marketing job, where Schmidt is later asked to guide Ed (Bob Gunton), a sixty-something intern, to avoid a company lawsuit over age discrimination.

An overabundance of Chinese food take-out menus left at the loft’s front door is the catalyst for an interconnected series of adventures for Jess and the guys.

Coach visits the apartment to spend a “guys night out” with the guys, after breaking up with his girlfriend. Nick going to a strip club with the guys, and telling her that they haven’t had a conversation about whether or not they’re boyfriend/girlfriend or are exclusive, upsets Jess to the point that she has “girls night out” with Cece at the bar.

Schmidt receives a series of recent e-mails from his favorite actor Michael Keaton, who has sent letters to Nick ever since he was a kid. However, it turns out those letters and e-mails were not from the actor but from Schmidt’s mother and Nick, posing as Keaton. Cece indulges in nightly parties to get over her break up with Schmidt.

Nick becomes irresponsible with the money from his late father’s estate, so Jess uses some of the money to pay Nick’s unpaid bills, behind his back. With Nick’s improved financial situation, Winston feels its finally time to ask Nick for the money he owes him.

Meanwhile, Winston psyches himself up for his huge surprise birthday celebration, which no one seemed to remember to throw for him.

Jess decides to throw Cece a surprise bachelorette party while Nick and Winston awkwardly take her fiancé, Shivrang, out for the night.

Nick and Schmidt go out on a “bro’s night,” but quickly become infatuated with, and highly competitive over, a beautiful woman attracted to sadness. Meanwhile, Winston falls for a girl with absolutely no interest in him, which only makes him more attracted to her. Then, Jess’ decision to have a night alone in the loft doesn’t go as planned and involves another round of the drinking game “True American,” and a surprising development in her relationship with one of the loft mates.
