Open with the most gripping moment you can — the pilot is your only chance to hook viewers. Information control is everything: reveal just enough to create understanding, withhold just enough to create obsession. The protagonist needs a personal stake in the thriller's central mystery, not just professional duty. Plant at least three questions in the pilot that won't be answered until later episodes. Trust is a scarce resource — establish which characters can be trusted and then undermine that. End the pilot with a revelation that completely reframes what the audience just watched.
Cold open with the event that launches the series — the crime, disappearance, or conspiracy revealed (3-5 pages). Act one establishes the protagonist and pulls them into the central mystery (12-15 pages). Act two deepens the mystery through investigation, introducing suspects and allies who may be neither (18-22 pages). Act three delivers the pilot's biggest twist and ends on a cliffhanger (12-15 pages). Target 55-65 pages.
Start with the question the audience will obsess over — then withhold the answer for as long as possible.
Outline your information reveals before writing. Map exactly what the audience learns and when.
Give your protagonist a personal stake in the outcome, not just a professional one.
Write your twist first, then go back and plant the clues that make it both surprising and inevitable.
