A man in a green jacket sits at a table, looking at a woman whose back is to the camera, as a figure in a dark, hooded costume with a white skull mask appears behind him and raises its hands. The scene cuts to a woman in a white lab coat raising her hands in alarm, then back to the man, who now looks at the masked figure standing behind him, while a hand reaches across the table toward a jar containing a worm.
