Some roads lead home.

Exit 9 leads somewhere else.

Daniel Mercer only wanted to avoid traffic.

Late at night, with his family asleep in the car, he takes a highway exit that should save them time. Instead, the GPS freezes. His phone loses its signal. The map becomes useless.

Then the road begins to repeat.

The same trees.

The same signs.

The same impossible exit.

EXIT 9.

Again.

And again.

Then Daniel sees another vehicle ahead.

A dark gray car.

It looks familiar.

Too familiar.

Because it is his own car.

As the family struggles to escape the impossible highway, they discover that they are not the first travelers to become trapped there. Every loop reveals another terrifying piece of the truth—and something is watching them from the darkness.

Something that knows their names.

Something that knows their memories.

And something that wants one of them to stay.

Daniel soon realizes that Exit 9 is not simply a road.

It is a doorway.

And every time he crosses it, the rules change.

To find his way home, Daniel must uncover what happened on the road years before—and confront the one thing he has spent his entire life refusing to remember.

Because the highway always comes back.

And this time, it wants Daniel to stay.
