Ma Tan Seong Ja

It's 1943. A sniper from the Korean Independence Army is given an impossible mission: he must destroy a divine object presented in a secret meeting between the Japanese authorities. He goes there and dies from suicide bombing.

60 years later. Professor Bae is a specialist in antics. She is asked to attend a secret auction to judge the authenticity of an old gun. But little does she know that she will awaken a spirit inhabiting the gun and live with it. Who is this mysterious spirit?
