Brooklyn, 1947: in the midst of a blizzard, in a two-family brownstone, two babies are born minutes apart to two women. They are sisters by marriage with an impenetrable bond forged before and during that dramatic night; but as the years progress, small cracks start to appear and their once deep friendship begins to unravel. No one knows why, and no one can stop it. One misguided choice; one moment of tragedy. Heartbreak wars with happiness and almost but not quite wins.
