In the dangerous world of tomb raiders, there are the people trying to bring them to justice. Heo Cho Hwi (Kim Sun Ah) has worked hard to move up in her career as an inspector in the Cultural Heritage Administration of Korea’s Theft Division by solving cases of stolen cultural artifacts. Her true motivation has been to find her father, a treasure hunter-thief who went missing seven years ago. Brought in to consult in Cho Hwi’s many tough cases is Kim Beom Sang (Lee Dong Gun), a university arts professor who can detect forgeries just by smelling it and restore original art pieces to mint condition. Beom Sang is ambitious and wants to make a name for himself but is repeatedly passed up for promotions because of his lack of family connections. With the help of high-tech gadgets, low-tech know-how and coworkers Wang Joo Hyun (Kim Jung Hwa) and Kang Shi Wan (Lee Joo Hyun), can Cho Hwi and Beom Sang find what they truly seek? “When It’s at Night” is a 2008 South Korean drama series directed by Son Hyung Suk..
