The Trills are under attack by the Gorns. The Enterprise, racing against the clock to intervene, is sent to the delta quadrant. Beverly crusher is badly injured but is desperately needed to fire the phasers, specially calibrated for a precise effect, but needs artificial intelligence module to do so. Troi helps by speaking to a Trill scientist who helps Troi performing a Quantum flux realignment while Beverly crusher is rendered unconcious. This allows Beverly crusher to fire the phasers, specially calibrated for a precise effect without artificial intelligence module, allowing the enterprise to help the Trills in time , saving the day.
