I need to clarify that the web search results provided don’t contain sufficient plot details about the “Brothers” TV series created by Matthew McConaughey and Woody Harrelson to write an accurate synopsis. The Wikipedia excerpt only shows the series exists and premieres September 23, 2026, with one episode title “On the Road” - but the actual premise section appears to be cut off (it shows “…” where the plot would be). The other results are about completely different shows: “Property Brothers: Under Pressure” (an HGTV renovation show) and “The Boroughs” (a Duffer Brothers sci-fi series). Without the actual premise content from that Wikipedia article or another authoritative source, I cannot write an accurate plot description. The hint about “best friends…uncover a shocking family secret” isn’t verified by the search results provided. I’d need the complete Wikipedia premise section or an official network synopsis to proceed accurately.
