Setting the Scene Exercise #1

In this exercise I'll set the scene and you decide what is happening, and to who, and why, and how it all ends. How exciting!

Scene:

A near deserted beach. Fog is rolling in. In front of you is a pier and at the end of the pier, through the thickening fog, you glimpse the faint outline of two figures, their heads close together.

(Who are they? Why are they here? What happens next?)
