Film Treatment
1. A film treatment (or treatment) is a piece of prose, typically the step between scene cards (index cards) and the first draft of a screenplay for a motion picture, television program, or radio play. It is generally longer and more detailed than an outline (or one-page synopsis), and it may include details of directorial style that an outline omits.
Treatments read like a short story, except they are told in the present tense and describe events as they happen.
