A routine drive turns into a nightmare when Lee Jung-soo, an ordinary salesman, finds himself trapped inside a collapsed tunnel. With nothing but his phone, a few bottles of water, and a birthday cake meant for his daughter, he must survive against impossible odds.

As rescue teams rush to dig through the wreckage, the world outside watches in suspense. With every passing day, hope dwindles, supplies run low, and desperation sets in. Bureaucratic delays and media frenzy turn his survival into a political spectacle—while Jung-soo fights for his life in the darkness.

But how long can a man last when the world is ready to move on?
From the director of A Hard Day, Tunnel is a gripping survival thriller that will leave you breathless.
“Buried alive. Time is running out.”
