The episode is told from the point of view of a housefly flying around the Sector V Treehouse, and is entirely orchestral, featuring no sound other than music which punctuates the action. The fly first witnesses Sector V arriving home from some mission, bringing back a Samurai helmet, apparently an item of great value to them. After cheering for their success, they all go to their rooms. When no one else is looking, Numbuh 1 takes the helmet on and pretends to battle in his room before he sees the fly. He runs away from it, seemingly scared of it. He then presses the emergency exit button, sucking the fly into an air vent.
