❗ This a sequel to Veteran (2015).

It's not my kind of movie at all. It's a classic detective movie, you shouldn't have too many expectations. Some friends said it's watchable just for the Korean actors, but I think the acting is mediocre. Of course, that's my personal opinion. The acting in this movie is mediocre, the effects are good, and the script is classic. If you like detective movies, watch it. Personally, I didn't like it.
