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. "Sorority Sisters" follows the lives of women from four different sororities. Since these 'sorors' are pledges for life, they are expected to continue their community work long after graduation. From long-awaited reunions, to managing the men in their lives, for these line sisters, it's homecoming all across the ATL. These ladies have a lot at stake - their aspirations, reputations, livelihoods, friendships, and families - and the legacies of their sororities.
