After coming home with a poor report card, Leo uses Davenport's award-winning memory erasing device to wipe Davenport's short term memory but inadvertently erases 25 years, rendering him a teenager.

In an effort to get out of training duties, Adam enlists Leo's help to create a duplicate Adam using Davenport's experimental cloning device. However, Adam's clone uses the same device to create another duplicate to avoid going to school and the clones he creates repeat the same process resulting in a mob of ever duplicating Adams.
