The Film is Based on a True Story in Almaty, Kazakhstan

- Hanaan took home the award for Best New Director at the Taipei Film Festival.
- Won the New Currents Award for the film Three: Not Over Yet at the 25th Busan International Film Festival.

First Stills Create Massive Buzz
Along with the cast reveal, the production also released its first official stills, which instantly triggered intrigue.
The stills show:
- Moon-seok in a tense life-or-death chase
