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.
