A comedy that answers the question of whether polar-opposite sisters can live together when one agrees to carry the other's baby. In the pilot, bright, optimistic, successful children's book editor Sarah turns to her estranged and free-spirited younger sister, Coco, when she learns she cannot conceive a child herself. Can this odd couple put their differences aside for the miracle of life? Coco decides to give it a try and packs up her bags and relocates from a friend's couch to move into her sister Sarah's enormous loft, but gets more than she bargained for when she discovers she is relegated to a dismal unfinished bedroom. Sarah's surprises continue with everything from an emergency Hello Kitty cell phone, to a visit from mom and dad; both of which take a turn for the worse.
