When Scott, a loving father of four, has his entire life's plan thrown into upheaval by a cancer diagnosis, he calls on a few of his closest allies to step in as back-up dads for every stage of his growing family's life. Scott assembles a trusted group of role models that includes Anthony, his oldest friend; Larry, his AA sponsor; and Oliver, his surgeon and best friend to his wife, Robin. These men agree to devote themselves to supporting and guiding Scott's amazing family through all the triumphs and challenges life has to offer – just in case he ever can't be there to do so himself.
