Pulp Fiction
Hey, you know that movie "Pulp Fiction" by Quentin Tarantino? Well, this has been bothering me for quite a while - what is in that briefcase??? I originally thought it was money, but that seems unfeasible when you think about how it was glowing, and how looking at it changed the robber's life.
dude it was a soul
Note that the combination to the briefcase was "666"
