Start from the beginning.
1 - Vanessa and Troy are walking out of the woods onto a parking lot-type thing. There is a single car in the parking lot (theirs). A cop car is driving by along the connecting rural road. Vanessa sees the car and tries to get its attention.
2 - Long shot of Vanessa and Troy running down the road after the cop car. Its brake lights flare.
3 - Repeat the long shot. Vanessa and Troy have caught up with the cop car and stand beside the driverside window.
VANESSA: Out in the woods! We saw--!
4 - Close on Vanessa and Troy. They both look terrified and sick. The cop car roof is visible, but not the interior.
VOICE (from within cop car): The woods?
5 - On the cop car driverside window. The bad dude from earlier is sitting in the front seat, wearing a cop uniform. He leans on the (lowered) window, a jovial expression on his face, although whether it's from being in a good mood or recognizing Vanessa and Troy is unclear. This panel could be done so as to leave space for title credits and the like, if desired.
BAD DUDE: ...what did you see?
