From partying down to growing up, a new night of original programming will spotlight two very different groups of Millennials as they navigate the highs and the lows of adulthood.

Party Down South returns for its wildest season yet on August 20 at 9 p.m. ET/PT, immediately followed by the series premiere of the coming-of-age docu-series Gainesville at 10:00 p.m. ET/PT. Gainesville picks up where Party Down South ends and highlights the next phase of life as a group of seven young friends transition into adulthood by banding together to face a broad range of issues, including paying for college and moving out of their parents’ house.

The evening kicks off with the original Party Down South cast – Daddy, Lyle, Murray, Walt, Hannah “Hott Dogg,” Lauren, Mattie and Tiffany – as they reunite in St. Petersburg, Florida, for a 10-episode season filled with adventure, partying and, of course, drama. Season four opens with one of the most heated fights in the show's history when Tiffany literally goes head-to-head with Hannah over her new boyfriend. In between the explosive fights and blooming relationships, an old flame comes into the picture resulting in a life-changing event for Lyle. Meanwhile, Walt and Murray find themselves hitting it off with the women of St. Pete, and “Martha” decides to crash her own birthday party.

Gainesville is a heartwarmingly honest depiction of seven young friends facing life on their own for the very first time. Life is a far cry from one big party for the tight group, as Andreya, Austin, Beth, Brian, Kenny, Kerryn and Shelby struggle to find their place in life. In each of the 10 half-hour episodes, the young friends will fight their way through devastating breakups, complex relationships and financial challenges facing most millennials today. One of Florida’s most renowned college towns, Gainesville is just their hometown. CMT will premiere back-to-back episodes of the new series on August 20 at 10 and 10:30 p.m. ET/PT.
