Tim Templeton is now an adult and lives with his wife Carol and their two daughters, 7-year-old Tabitha and infant Tina. Tim's younger brother Ted is a successful CEO and is always absent. One night, Tim discovers that Tina comes from Baby Corp, just as how Ted did, and that she has been assigned for a "special mission" that requires Ted's presence. Tim refuses to call Ted, saying that he will never come. However, Tina leaves a fake voicemail for Ted, luring him to the Templetons' house.
The next morning, Ted arrives and Tim explains to him that Tina is a Baby Corp dispatch. Tina introduces the brothers to a new formula that will allow them to turn back into children for 48 hours in order to infiltrate Tabitha's school and figure out what Dr. Erwin Armstrong, founder and principal of the Acorn Center for Advanced Childhood is planning behind parents' backs.
At the school, Tim, now as his 7-year-old self, follows Tabitha to her class while baby Ted is placed with other babies. Ted rallies the babies to help him get out of the playroom so that he can go to Armstrong's office to investigate. Tim tries to get sent to the principal's office by disrupting class, but is instead put in "The Box" for timeout. Ted discovers that Armstrong is actually a baby himself, having run away from home after realizing that he was smarter than his parents and now makes money by creating popular phone apps. His ultimate plan is to get rid of every parent on B-Day, so that they cannot tell their children what to do anymore.
On the night of a holiday pageant, where Tabitha is supposed to sing a solo, the brothers and Tina plan to expose Armstrong. However, they learn that B-Day is set to happen that night through Armstrong's new app, QT-Snap, which will hypnotize the parents into mindless zombies. Both Tim and Ted are caught by Armstrong's ninja babies and are put in The Box, which slowly starts to fill with water. Tabitha performs her solo, but when she sees that Tim has not shown up, she runs off the stage crying. She is consoled by Tina, who reveals her identity and her mission. Tabitha agrees to help her younger sister by getting to the server and shutting down QT-Snap before it can go worldwide. Tim and Ted escape from The Box with the help of Tabitha's pet pony Precious.
Tim and Ted reach the server first, but they are stopped by Armstrong, who calls the zombie parents for backup. While the brothers hold them back as the formula starts to wear off, Tina and Tabitha get up to the server. Tabitha is able to hack in and pull up the shutdown screen, but is interrupted by Armstrong. The sisters then set off a candy lava volcano using Mentos and soda, destroying the servers and turning all parents back to normal. Tina then reveals that bringing Tim and Ted back together was her true mission. The whole Templeton family gathers to celebrate Christmas, while Armstrong returns to his own family.
