Mary Mary is a Grammy-winning gospel duo comprised of sisters Erica and Tina Campbell. The sisters are busy career women as they tour the country promoting their album and walking down Hollywood red carpets. But out of the spotlight, they are wives and mothers trying to balance family life with their superstar lifestyles. It's not easy for family members to work together -- especially when in the spotlight -- and over time, betrayals and other obstacles lead to Mary Mary separating and the ladies pursuing solo careers.
