EXT. THICK WOODS - NIGHT (or DAY, either one)

PANTING. Feet RUNNING and STUMBLING.

A GIRL (18-24) races for her life from an UNSEEN PURSUER.

She DIES. With a SCREAM. 

And then we switch to somewhere else and meet the protagonist doing something mundane.

If you have written this, you are NOT ALONE. Word to the wise.
