The Tower (2012 South Korean film)

[5] Lee Dae-ho is a single father and manager of Tower Sky, a 120-story luxurious twin-tower building complex located in Yeouido, Seoul.

A team of firefighters arrives at the scene, led by Captain Kang Young-ki, who joined at the last minute despite being off-duty, including Sergeant Oh Byung-man and rookie fireman Lee Sun-woo.

Dae-ho leads the firefighting team through the quickest path to the server room where the helicopter crashed, and Young-ki hands him a radio and an oxygen mask so that he can go search for his daughter.

In an attempt to stop the fire from spreading, Jo decides to activate the firewalls, leaving Dae-ho, who finally reunited with Ha-na and the rest of the survivors, as well as many other people, trapped within the blazing floors.

Dae-ho, under Yoon-hee's suggestion, directs the trapped survivors to jump onto the gondola in order to escape, but an elderly couple perishes during their descent, and Young-ki euthanizes a critically injured victim using morphine.

They leave the survivors on the storm drain and set out to detonate the rainwater storage tanks, hoping the fast-moving current will send them straight towards the Han River before the tower collapses.

Young-ki then sacrifices his own life by manually detonating the explosives, and the resulting rushing torrent carries the group towards the river, right as the firefighters blow up the Riverview Tower.

[2] On its theater release on December 25, 2012, The Tower drew 431,759 admissions, the second highest opening day ticket sales in the history of Korean cinema (after The Thieves' 436,628).
