The Parks Department is throwing a charity auction to raise money for the Unity Concert, which is only three weeks away. They hope to raise a minimum of $30,000 or otherwise they will be in trouble. While Leslie Knope and Ben Wyatt are in charge of organizing the auction, they are somewhat distracted with Leslie's pregnancy and are set to meet with Dr. Saperstein for an ultrasound examination. They are shocked to find out that Leslie is in fact carrying triplets, and are told by Saperstein to take it easy over the coming months in order to avoid stress. In the wake of the news, Ben crunches the numbers and can't fathom how he and Leslie are going to be able to survive taking care of three children.
At the charity auction, Leslie sheds her ruthless ways to be as calm as she can be. This does not bode well for the auction as she is unable to get those in attendance to fork out an appropriate amount of money for the items due to her calm demeanour. After selling a guitar signed by the Red Hot Chilli Peppers for a mere $50, Ben jostles with the buyer and ends up with a hand injury. Ben and Leslie's failed attempts at trying to remove stress leads to Ben lamenting over how much raising three children is going to cost, adding to the fact that they recently spent their entire savings account on a trip to Paris. Ben begins to panic over their situation, but is comforted by Leslie who explains that everything they have been through has been preparation for this moment, hence why Leslie feels she is finally equipped to handle such stress.
Meanwhile, Ron Swanson recruits Donna Meagle to accompany him to Nick Newport Elementary School, the school where his two step-daughters attend, to help make costumes for the Unity Concert's youth review segment. Donna only agrees on the condition that Ron keeps her ex-boyfriend, Joe, away from her; Joe works at the school and she considers him a nightmare. At the school, Donna quickly bumps into Joe. Ron does his duty and steps in between them, but as the day goes on, he comes to realize what a kind, genuine person Joe really is. Ron admits to Donna that he likes Joe and doesn't understand Donna's problem with him. Donna explains that she is a social butterfly and can't stand Joe constantly pampering her when they are together. Ron encourages Donna to not confuse drama with happiness. She heeds to his advice and confronts Joe. She lays down some ground rules with him for the future regarding her alone time and the two arrange dinner together.
Elsewhere, Andy Dwyer is still holding onto Leslie's pregnancy secret and does his best to avoid discussing the matter with April Ludgate. To make matters worse for Andy, he has a hectic schedule over the coming days with a number of Johnny Karate shows to perform. To stop April from asking, Andy falsely tells her that his secret is that Jerry Gergich has a deadly disease. April falls for it and in turn, begins feeling sorry for Jerry. She decides to be nice to Jerry and spends time talking with him, thinking she ought to make a mends if he is dying. Upon finding out that Andy lied, she is furious at him. Andy stays strong though and does not budge on revealing the secret.
The episode ends with Leslie admitting to the office that the reason she has been acting so weird is because she has been hiding the fact that she is pregnant. The entire office is thrilled for her, especially Andy, with the weight of the secret now off his shoulders. Their big reveal that they are having triplets is first met with shock, but is then followed up with many offers to assist in general baby needs, such as clothes, cribs, pre-school hook ups, and babysitting. Ben and Leslie are overjoyed by their friends' generosity and can go forth knowing they have a tight support network around them. Craig Middlebrooks also announces that he sold everything on the auction list.
