Numbuh 1 is enjoying a nice day of fishing with his father. But is interrupted by Numbuh 86. He is sent to be decommissioned immediately. 1 tells that it's a mistake. 86 doesn't listen and her troops start to capture #1. Numbuh 1 escapes from 86. Numbuh 1 heads for the treehouse, but Numbuh 86 is already there. She pushes a button and the treehouse starts to fly off. #1 gets away and meets Numbuh 274. As Nigel meets him, he sees Numbuh 86 with Numbuh's 2,3,4 and 5 being taken away. 274 tells him to rescue them anyway he can. #1 goes and visits Numbuh 2's little brother, Tommy. Tommy devices a ship to travel to The Moon Base. While on Moon Base, 2,3,4 and 5 are being decommissioned. 86 still won't listen to what they have to say. As Numbuh 1 gets to Moon Base, he realizes he is too late and his team have been decommissioned. Since 2,3,4 and 5 have had memories erased, they have no idea whats going on. As 86 starts attacking again, Nigel and his team crash down to 274's office. Numbuh pulls out an envelope and shows it to 86. She is horrified that Chad was going to have his 13th birthday. Nigel explains that since 274 was going to turn 13, he was going to up the ages of EVERY operative so no one would find out his age. Numbuh 274 shouts that he has ran the organization for 5 years and it can't run itself. Chad then presses a button and says he has sent the Moon Base into the sun and takes Tommy hostage. He escapes. Numbuh 5 then comes up with a plan to save the Moon Base. The team build a catapult that launches Numbuh 4 in to Chad's ship. Numbuh 4 takes out 274. Then Tommy takes the Base back to the moon. Everyone is saved. 274 is left in a prison. Cree shows up and explains her plan. Chad says it failed. Cree then leaves and 274 teamed up with her.
