David, an orderly at a hospital, tells his horrific story of being kidnapped and forced to play a vile game of survival.

Saw (retrospectively also known as Saw 0.5) is an Australian short subject horror film, released in 2003. It was directed by James Wan and written by Wan and Leigh Whannell, the latter also starring in it. It was originally used to pitch their script for a full-length feature film of the same name to various studios and actors. The full-length film was eventually made in 2004. The short film later became a scene in Saw, with Shawnee Smith as Amanda Young wearing the Reverse Bear Trap device instead of David. The original short can be viewed on the second disc of Saw: Uncut Edition.

David, un médico del hospital de la ciudad, cuenta a la policía su terrible historia: fue capturado por un psicópata que le obligó a jugar a un macabro juego de supervivencia. Cortometraje que derivó en la famosa película de 2004 "Saw", con idéntico reparto y equipo técnico y que sirvió de inicio a una de las sagas de terror más rentables de la historia del cine.
