The contents of the briefcase in Pulp Fiction are never revealed in the movie, and director Quentin Tarantino has suggested that there is no concrete answer. The briefcase is a plot device used to push the story forward, and it is a classic example of a MacGuffin. A MacGuffin is an object that propels a story forward but has no bearing on the story whatsoever. Despite this, many theories have been proposed over the years about what could be inside the briefcase, ranging from the basic to the outrageous. Some of the most popular theories include:
- Marcellus Wallaces soul
- Gold bars
- Diamonds
- Elvis Presley's golden suit
- A light bulb
- Nothing
However, none of these theories have been confirmed by Tarantino or anyone else involved in the making of the movie.
