LENOX — During that tumultuous era of civil rights struggles that was the 1960s — and perhaps still is — carloads of Black and white women drove Cadillacs around the American South talking with women in their living rooms about voting and standing up to the injustices in their lives.

Award-winning Boston playwright Tori Sampson turned this little-known story into the play “Cadillac Crew,” now receiving only its second professional production by WAM Theatre at Shakespeare & Company’s Tina Packer Playhouse through Oct. 29.
