Tunnel

An ordinary car dealer named Jung-Soo (Jung-woo Ha) is on his way home with a birthday cake for his daughter when something extraordinary happens. As he's driving through a tunnel, it suddenly collapses on him, leaving him trapped.

A massive rescue effort is immediately organized with little time to spare, as his cell phone quickly drains power, and his food, water, and oxygen dwindles. After a series of blunders delay the rescue operation, Jung-Soo, his family, and the nation begin to lose to hope.
