As this Korean drama opens a sniper is trying to kill Jeong Ji-an, a young woman in a remote house; she finds a rifle under a sofa and fires back. We then, via a series of flashbacks see how she came to be there and why she is being targeted. It turns out that her parents had been killed and she when she was a young girl and she was adopted her uncle, Jeong Jin-man. Officially he runs a business selling tubing but in reality it is a front for an illegal weapons 'supermarket'; following his apparent suicide she has inherited the business... which came as a surprise to her.
I really enjoyed this action packed series. The opening scene immediately grabbed my attention before flashbacks start telling us how the situation occurred. Throughout the series we move between various time periods but is never confusing about when what we are seeing is going on. This means that even though Jeong Jin-man is dead when the series starts he is still a major character. The acting is solid throughout; the main bad guy may be a bit of a pantomime villain but that suits the feel of the series. The final episode wraps things up nicely without shutting down the possibility of another season. Overall I'd definitely recommend this to action fans.
