It is a cheap plot device to show what Ezri is thinking and it really makes for a bad episode-almost as bad as the terrible one where they played baseball on the holodeck. Field of Fire is a roleplaying community set in the world of A Song of Ice and Fire made by George R. The biggest problem is the dumb plot device of having Ezri standing around having a conversation with her fellow crime fighter who you see standing with her, talking out the crime with her.
Together, these crime fighters go off on an adventure.and a dumb one at that- especially regarding the murderer and his motivations. And, to assist her is her alter-ego-the previous incarnation who was a murderer. The Field of Fire of a weapon (or group of weapons) is the area around it that can easily and effectively be reached by gunfire.
So, as Ezri Dax hasn't yet established herself as an important member of the crew yet (just an insecure and wimpy one), she decides to play Nancy Drew, Girl Detective and go in search of the killer (isn't what Odo and Worf are for on the station?!). It begins with a senseless murder on DS9 and no one knows who did it. Field Of Fire: A C, Kansas Prairie WildflowersClenton E.
"Field of Fire" is a truly bad episode of "Star Trek: Deep Space 9" and it's one I hope never to see again.
