SUMMARY
This drama will hit you HARD on the suspense. Want an good action and mystery hitter? I recommend this one because it is packed with it. Part of the enjoyment comes from the quest of finding out the truth or who the real culprit is. As our protagonist, Cha Dal Geon uncover details of a horrific plane crash, fighting his way through mercenaries and lobbyists, numerous plot twists will arise. Unfortunately, the plot does get progressively messy as the story unfolds and you may start questioning its legitimacy. Outcomes of some scenes also feel very unbelievable and not every detail in the story is explained properly. Fortunately, the performance of the main cast is impressive; their characters are likeable, sensible and relatable to the situations they face. Combined with well-produced action sequences, it becomes easy for us viewers to turn a blind eye or two on some of the crazy showdown that just happened, as unrealistic as they are. Some people will find the plot made to be too edgy especially towards the last couple of episodes. Regardless of how important movie logic is to you, it is still a very compelling plot and definitely worth the hours to watch.
