To many people, a family consists of those related by blood, but to others family has a much deeper meaning. Through a tragic turn of events the Garcias, Knights, Diamonds, and Mitchells - four families who have been lifelong friends - must stand together and lean on one another when one of their own is taken from them by someone they trusted. Along the way, they prove that sometimes you don't need blood to be a family. All you need is love.
