It concerns an unnamed protagonist's obsessive quest to learn all he can about a mysterious film called Throat Sprockets.

As fixation on the film consumes his personal life, he develops a sexual fetish for women's throats, an affinity which begins spreading to global and apocalyptic proportions, as the film's cult status and legend grows.

Throat Sprockets began life as a graphic novel, written by Lucas and illustrated by Mike Hoffman.

Since its publication, Throat Sprockets has been singled out as one of the outstanding works of contemporary horror fiction by two reference books, Dark Thoughts by Stanley Wiater and Horror: Another 100 Best Books edited by Stephen Jones and Kim Newman.

In October 2006, Rue Morgue magazine included Throat Sprockets on their list of 50 essential alternative horror novels.
