One Breakdown Sheet is normally equivalent to one scene, but does not necessarily need to be the case. Each Sheet contains a list of Breakdown Items required to shoot the specified scene. Each Sheet also contains a location where the scene will be filmed. Note that this is different from the Set which is an element of the script. In other words, if you are filming a (castle) interior at (Downtown Studio 8) then the Location will be named "Downtown Studio 8" and the Set will be named "Castle".
