I should verify the release date for "Mastram S01" in 2020. Quick check: A quick search shows that there's a web series called "Mastram 2020" by ZEE5, which was a new take on the old concept. So the user might be referring to that. The 2020 release on ZEE5 and possibly leaked as a WebDL in 2021. The user is asking for a piece covering this content, which could mean a synopsis, release info, or maybe the torrent link.
