A weekend camping trip to the Hoia Baciu forest ends before it properly begins. A detour down a ravine, a shaky bridge, a car plunging into water — everyone survives, but the vehicle is destroyed and there is no signal. Night is falling fast. The only option is to walk through the forest to reach the nearby town of Cluj. The forest is not cooperative. Sounds carry in wrong directions. Mistakes are fatal. Something in the dark is aware of your group's presence, and silence may be your only real protection.
