Intercutting

Some scripts may use the term INTERCUT BETWEEN. At this point, two scenes will be shown a few moments each, back and forth. For example, if Laura is stuck in her flaming house and the fire department in on the way, a screenplay may call for intercutting between the flames closing in on Laura and the fire fighters riding across town to save her.
Note: this is a style that can be written around with standard scene breaks. It's more to prepare the reader for the upcoming slug line bonanza.

An editing method whereby related shots are inserted into a series of other shots for the purpose of contrast or for some other effect. (Film Editing)
