Set in 1977, “Showing Roots” explores the pent up racial tensions of a small town through the eyes of two women (Maggie Grace, “Taken” and Uzo Aduba, “Orange is the New Black”), who work together at the local beauty parlor. They forge an unlikely friendship and become inspired to integrate their town when the miniseries “Roots” hits the airwaves – much to the dismay of those around them. Rounding out the all-star cast are Elizabeth McGovern (“Downton Abbey”), Adam Brody (“The O.C.”) and Cicely Tyson (“The Trip to Bountiful”), who starred in the original “Roots.”
