VH1 gives viewers a rare glimpse into the unique world of ATL Greek life with the series premiere of "Sorority Sisters" on Monday, December 15 at 9:00 PM ET/PT. Nine women, who continue to honor the traditions and legacies of their respective sororities and chapters, all agree on one main principle: sisterhood doesn't end after graduation, it's for life. For these friends and sisters (or 'sorors') from celebrated historically black colleges and universities in Atlanta, strong ties to their organizations lead to fierce rivalries, but through thick and thin, these women stand united and share an unbreakable bond.
