Complete story — includes the ending
An emergency response drill interrupts Leslie and Ben's fundraising gala for the Commons, while Andy prepares for his Police Academy exam. After Councilman Jamm sabotages the drill, asking the state representative to make the drill longer than it has to be, Ben takes over planning the gala. Leslie goes along with the drill until she realizes Jamm's scheme, when she decides to "kill" the whole town to end the drill sooner. She returns to the gala where Ben suggests they get married that night.
