The gang is preparing for the annual "Up Late" live Christmas special with, special guest Mindy Kaling. Animal is in charge of tinsel, Sweetums hangs the lights, Sam Eagle strategically places the mistletoe - everything is in order. Or so it seems. Meanwhile, Miss Piggy offers relationship advice to Fozzie, which forces her to reevaluate her relationship with Kermit. Yolanda rigs the Secret Santa gift exchange, and Echosmith performs at the crew's Christmas party.

When Miss Piggy suffers a scandalous wardrobe malfunction, the network is outraged, and Piggy is forced to question everything she stands for, but Kermit and the gang rally together and come to her defense. Meanwhile, Gonzo misses his ex-girlfriend Camilla, so Pepe and Rizzo decide to throw a house party to cheer him up.
