When the world collapses, rules no longer matter... except the one you should never have broken.
A strange event buries the city and turns everything into an intricate, deadly underground labyrinth. You find yourself trapped with Nicole, the woman you should never have fallen in love with: your best friend's mother.
As you search for a way out amid unstable tunnels and the fear of being left in the dark, forced proximity erodes morale. Every glance weighs heavily. Every silence screams. And every decision can save them... or condemn them.
