Subject is a series of commentary shot by CCTV, recounting the espionage between CCP and KMT during early 50's.  It was a period of so-called "White Terror" that'd had long repercussions on Taiwan's politics and the mindset toward Mainland, even till now.  Please log on Youtube to find the series, and it's really worth your while to watch them.
