This is the 2015 Korean TV series, Hangul RR "Seupai."

Wikipedia: https://en.wikipedia.org/wiki/Spy_(2015_TV_series) "The fictional story begins after the execution of real-life North Korean general Jang Sung-taek. One day an order comes down from North Korea, reactivating erstwhile spy Park Hye-rim who has spent decades in South Korea as an ordinary housewife. She is given the mission to turn and bring in her own son, Kim Sun-woo. Cool-headed, quick-witted genius Sun-woo is an information analyst on North Korea working for the NIS. His girlfriend Yoon-jin is a tour guide for Chinese tourists who cannot speak Chinese, and they fell in love when Sun-woo helped her translate. Hye-rim is suddenly forced to choose between her son and country, and risks her life to see the choice through."

This is the full set of 16 episodes with edited "soft" English captions; that is, English subtitles are part of the file but will not appear in the video unless you enable subtitles. The episodes are each about 45 minutes in length, the shortest being 41 minutes and the longest 49 minutes.

I downloaded the "720p.HDTV.x264.Film.iVTC.AAC-SODiHD" source files and downloaded "HDTV.H264.720p-LIMO" Viki subtitles from subscene.com. Then I...

• "Softened" subtitled profanity (bastard --> jerk, damn --> darn, bitch --> wench etc.)
• Converted various units & words to U.S. equivalents if appropriate
• Corrected other commonly-found typos
• Used Subtitle Edit to find and fix all flagged issues
• Watched the series and made further corrections
• Used a linear video editor to mask the occasional scrolling news/ads that appear at the bottom of the screen on many episodes
• Re-processed the videos using Handbrake to add the subtitles as "soft" (not burned in) subtitles
