Kim and her mom haven't had some mother daughter time in a while. Mr. Dr. Possible deals with the twins so that mom and daughter can have time together. So they decide to spend a day together and what better day than Mother's Day? But duty calls for Kim as Drakken is once again trying to steal a special matter eating synthol. This time rather than Ron it is Kim's mom who accompanies Kim on her mission to thwart Drakken's theft on a train. However Drakken is also entertaining his mother and trying to get her to think that he is on an outing/picnic. She thinks that her son is a radio show shrink but blissfully unaware that he is in reality some villain bent on world domination. His mother not only embarrasses him in front of Shego and a couple of henchmen but spoils the plan by opening and activating the substance that begins consuming material and growing. Fortunately Mrs. Dr. Possible's surgery skills come in to save the day more than once. Ultimately Drakken is foiled by his own mother in order to preserve the secret him being villain bent on world conquest. Later they send the matter eating mess to the Stoppable residence where it eats all the junk in the garage and thus providing Ron's mom with a gift of a clean/empty garage (except for that blasted garden gnome that haunted him during his childhood).
