The document provides a 21-shot list for a trailer, including descriptions of shots such as a clock ticking, flashbacks of a father being dragged and a mother screaming, a husband exiting a hotel and receiving a text, a woman watching a rom-com, footsteps of a killer walking, and the woman being taken hostage by the killer in her home. The document also provides context that a shot list helps envision how a screenplay will look on screen and is part of pre-production planning to make the filming process clearer and save time.
