It's a special day at T.U.F.F. headquarters where they await the arrival of top former T.U.F.F. Agent Jack Rabbit. Jack makes it clear that he has more on his agenda than just visiting his former agency, and tries to convince his old partner, Kitty, to join his new agency, S.T.U.F.F. (Super Turbo Undercover Fighting Force). Jack proceeds to take Kitty out on a date to catch up and to try to convince Kitty to abandon T.U.F.F. Dudley grows jealous of everyone showering Jack with attention and awe, and eventually those feelings give way to suspicion. Dudley acts on his suspicions and spies on Kitty and Jack. Keswick accompanies Dudley on his mission to spy on Jack and Kitty, and are caught each time. Kitty becomes annoyed that Dudley and Keswick do not trust her, and because of this, considers touring S.T.U.F.F. Dudley continues spying on Jack and discovers he is working with Snaptrap to kidnap Kitty. However, Jack tricks Dudley into thinking he is apprehending Snaptrap, so Dudley goes to S.T.U.F.F. to apologize to Kitty. Before he can, he discovers the D.O.O.M. Buggy outside the headquarters, and immediately senses a problem. Dudley and Keswick raid the headquarters and discover Kitty is having her brain drained by Jack so he could sell the secret information of T.U.F.F. to villains. As Snaptrap delivers the money to Jack Rabbit (in his mother's purse), Dudley and Keswick bust in and the fight to save Kitty ensues. At first, Jack has the upper hand in martial arts and easily overpowers Dudley. Just as he is about to finish him off, Keswick, who previously fled in response to a glare from Snaptrap, bursts through the wall with his fudge-gattling gun. Jack Rabbit dodges the ice cream in a scene referential of the Matrix's bullet-time, but Dudley takes the upper hand and delivers a signature Puppy Punch to Jack. However, Dudley sees the Brain Drain is at 100%, so he blasts the helmet and cuffs. Then he does a little romantic dance with Kitty before spinning her out of the room. Dudley walks away, whistling, while Keswick traps Snaptrap in a mound of fudge. Dudley and co. return to T.U.F.F. having apprehended the villains Jack and Snaptrap, and the episode draws to a close with Kitty thanking Dudley for saving her, telling him he's the best secret agent she could ask for, and Dudley playing some "victory theme music" on his cuff, of which the music stops and has Peg Puppy telling him to clean his room.
