This is the 2024 Korean action/thriller/mystery/comedy drama series. Its native title is "크래시" which is just the Hangul transliteration of the English title.

This is the complete set of 12 episodes ranging from 60 to 64 minutes long each. They all have edited "soft" English captions; that is, English subtitles are part of the MKV file and the subtitles can be enabled or disabled as you wish.

I downloaded the source videos named like "Crash.S01E01.1080p.DSNP.WEB-DL.H264.AAC-ADWeb.mkv" and extracted the English subtitles from them. Then I...
- Used Subtitle Edit (by Nikolaj Lynge Olsson) to find and fix all flagged issues
- Added 0.7 second to each subtitle (where possible) to allow more time to read them and adjusted words/minute to at least 280
- "Softened" all subtitled profanity (bastard --> jerk, damn --> darn, bitch --> witch etc.)
- Corrected commonly-found typos, converted Korean Won amounts into American Dollars, converted British terms to American ones, and converted Korean names to AP style (family name followed by hyphenated given name)
- Used Handbrake to create new MKV files using my subtitles
