PIcard, Ro, Guinen, and Keiko are accidentally filtered through an ion cloud. When they are transported on board they have returned to their childhood body, but with all their adult intelligences intact. This is a puzzle for sure, but when a couple Klingon vessels attack and ultimately board the ship, they have bigger troubles. As it turns out, it is not the Klingons; it is a group of Ferengi rogues who have commandeered the old Klingon vessels and now have moved on to the Enterprise, the purpose to sell it to the Romulans. The regular crew is transported to a planet that was to be explored and the children are left behind, among them the four mini-adults. Of course, the plot takes an expected route when the Ferengi begin to be too comfortable on the ship, full of themselves as usual. It allows the children (who are in grave danger) to begin a plot that feeds off the stupidity of the Ferengi. This is one of those just plain fun episodes that isn't to be taken too seriously, but there is still an element of danger.
