During Japanese colonial rule (1910-1945), Korean independence activists established the Provisional Government of the Republic of Korea. This year marks the 100th anniversary of the Provisional Government. Even to this day, Korea and Japan are in constant conflict over unresolved historical issues, most notably the comfort women. Hence, the pro-Japanese issues remain an important agenda for the Korean government. Although various research has been conducted on these pro-Japanese groups, there is a dearth of studies on Korean spies who hid their identity and collaborated with the Japanese, with very few academic papers on the subject. The KBS documentary seeks to illuminate the true nature of the Korean spies who had infiltrated the independence movement camp and sold out their own people to the Japanese.
