23 Jump Street Christmas Undercover 2025
Starring Jonah Hill, Channing Tatum, and Brie Larson
The holiday season is about to get significantly more dangerous and exponentially dumber as officers Schmidt and Jenko return for a brand new mission. This sequel is stuffed to the brim with undercover chaos, wild disguises, and enough festive mayhem to shake the snow right off the North Pole.

The trouble begins after a disastrous mandatory sensitivity training session at headquarters. The meeting concludes in absolute catastrophe, resulting in a completely destroyed precinct Christmas tree and a physical altercation with a very angry administrative elf. As punishment for their antics, Captain Dickson reassigns Schmidt and Jenko to a bizarre special seasonal operation. They are sent to infiltrate a holiday pop-up high school specifically designed for troubled teens, where a dangerous brand new synthetic candy drug known on the streets as Jingle Jolt is rapidly sweeping through the hallways.

In true Jump Street fashion, their integration into the student body is anything but smooth. Schmidt arrives on campus squeezed into an ugly Christmas sweater that is at least two sizes too small, attempting to blend in as a sensitive artsy transfer student with a strange passion for gingerbread based social activism. Meanwhile, Jenko takes a different approach, instantly becoming the star athlete on the schools snow covered football field, mostly because he is easily distracted and thinks the atmospheric snow machines are actually super cool rocket clouds.

As they dive deeper into the case, the personal stakes rise. Schmidt awkwardly crosses paths with Molly, played by Brie Larson, who has returned not as a student but as a skeptical teacher at the school. Her holiday spirit is severely tested by Schmidts overwhelming incompetence and bizarre behavior. On the other side of the cafeteria, Jenko accidentally befriends the prime suspect of the investigation, a charismatic and popular student who is secretly planning the largest and most illegal Christmas rave the city has ever seen.
The investigation spirals out of control with a series of festive disasters. Between dodging exploding glass ornaments, surviving a disastrous undercover caroling mission that alerts the entire neighborhood, fighting off a ruthless gang of rogue Santas, and tracking down one extremely suspicious reindeer mascot, the duo has their hands full. They must figure out who is behind the Jingle Jolt distribution network before the clock strikes midnight on Christmas Eve. If they fail, the entire city faces the threat of spiraling into absolute candy fueled chaos.
Packed with outrageous humor, over the top action sequences, and a heavy dose of festive absurdity, Christmas Undercover brings the heat with irreverent charm. In this world, the season is not about peace and joy; it is about going undercover, messing absolutely everything up, and somehow still managing to save the day.
