Leo earns a place on the station by becoming the GSA's newest recruit, to be trained under Kai (who finds being in change of his Red Ranger leader more than a little awkward). Leo's lack of discipline allows Horn, a weapons master monster, to abscond with all the station's weaponry, but Horn's true objective is the capture of the Quasar Sabers. Fortunately, the Quasar Sabors have other plans.
