With a production budget of about 30 billion won, this 10-episode crime action film has attracted great attention since before its release.
Trigger is set in fictional Korea, a country famous for its strict gun and bullet control laws. But a new wave of crime suddenly arose, when illegal guns from mysterious sources began to flood into the country, reaching the hands of the people. Chaos has occurred, pushing the number of gun-related cases to the alarm level.
In that context, Lee Do (played by actor Kim Nam Gil) - a former street striper who has now become a regular police officer - determined to fight against the wave of violence, hunting for smugglers.
Meanwhile, Kim Young Kwang plays Moon Baek - Lee Do's mysterious ally. He exudes a free and comfortable look, but is actually a powerful figure in the arms trafficking world, unpredictable and full of secrets.

Director Kwon Oh Sung explained that the idea of the film comes from the idea of how Korean society would react if guns and bullets were suddenly provided, and what choice people would make in such a world.
When making each episode, we focus on situations where people can truly sympathize. The gun-held characters are not extraordinary or extreme - they are the ordinary people you can meet in your daily life, the director shared.
He added: Unlike the flashy action films that only consider guns as entertainment, this work has adapted action scenes to suit each character, focusing on their emotions, situations and attitudes to create realistic and emotional shooting scenes.
Actor Kim Nam Gil also said: The film does not take bullets lightly, instead, the film uses them as symbols to explore human nature and social structure.
Although it is an action film series, The gun also feels like a psychological film, raising questions about how far a person can fall, and what they can still protect.
Before its release, Netflix aired its first 4 episodes to the media and received compliments for its thrilling atmosphere and "addictive" pace.
"The gun" is expected to continue the success of popular Korean action and thrillers recently on Netflix such as "Khong Duong Thu", "Nguoi Lam Than 2"...
