This is an action/crime/noir drama revolving around a drug cartel and the undercover agents assigned to infiltrate that organization. It's fast paced with well thought out character developments/back stories. I went into watching this series with minimal information and I am glad I did. There are layers upon layers of mystery that once peeled back, nothing is what it seems. Granted, some details and points do not make sense; overall though, it is pretty amazing for k-drama. The main character of "Doctor's Son" is ambitious and calculating. Just get used to him waltzing in to get it done. Pretty cool. Just remember to watch through the end credit in the final episode for an additional teaser. What does it mean?!? >**<
