It started with a hijacking.
When two runaway teens stole Jason Murich's car, they dragged him into a high-speed chase through the streets of L.A. But when the roads ran out, the only place left to hide was underground.
Beneath the city lay a world of crumbling tunnels, buried secrets, and something far more dangerous than police sirens.
And as the three descended deeper, Jason began to realize-they weren't just running from something.
They were running toward it.
And the further down they went...
the harder it became to crawl back up.
