Kim Je-ha is a former mercenary soldier for the PMC Blackstone. While in Iraq, he gets framed for the murder of his lover Raniya, a civilian. As a result, he runs away and becomes a fugitive.

He accepts the job in exchange for resources that he needs in order to get his revenge on another presidential candidate, Park Kwan-soo, who previously ordered the killing of his lover.

In the meantime, Je-ha gets assigned to guard Go An-na, the hidden daughter of Jang Se-joon, whose life is always threatened because of Yoo-jin, her stepmother. An-na, who has been reclused and lonely all her life, starts relying on Je-ha, who shows concern for her and protects her at all costs.

They slowly fall in love with each other, which makes Je-ha torn between having to work with his ally, Yoo-jin, in order to get his revenge and protecting his new found love, An-na, against his own ally.

The drama is written by scriptwriter Jang Hyuk-rin, who wrote Yong-pal (2015) and directed by Kwak Jung-hwan of Neighbourhood Hero (2016).

Being depicted with a bodyguard action theme, the drama utilised various fighting techniques including systema, taekwondo, aikido, and jujutsu for its action scenes. It became the first Korean television drama to introduce the Bullet Time effect.

The first script reading was held in August 2016 at the CJ E&M Centre in Seoul, South Korea. Filming began in September.

Some scenes of the drama, primarily in episodes 1 and 2, were filmed in Catalonia (along the mountain of Montserrat, the Gothic and Baroque Cistercian Monastery of Santes Creus in Aiguamúrcia), followed by various places in Barcelona (center, Old City, etc., as well as various metro / commuter rail stations such as Plaça d’Espanya and Magòria / La Campana), Gaudí’s Modernista Colònia Güell Crypt (fashion show party) among other locations in Spain (probably near Almería for the Iraq War desert locations). The closing scene of episode 16 was filmed at Barcelona’s Turó de la Rovira hill. The rest of the series was apparently filmed in Korea.

The male lead Ji Chang-wook, due to his casting, became the highest-paid actor for a tvN drama. He had special training and performed the action stunts in the drama by himself, without a body double. At the press conference, director Kwak expressed “On top of Ji’s splendid action, the drama will tell the story of insatiable desire and political fights between people holding secrets of their own.”


The drama received favorable reviews, topping cable channel viewership ratings throughout its 8-week broadcast.

It was praised by viewers for good performances.

International Broadcast

The drama streams internationally on DramaFever with English subtitles. Its broadcasting rights were sold to Vietnam, Taiwan, Hong Kong, Japan, Singapore, Indonesia, Malaysia, Philippines, China, Thailand, Israel and Greece.
