Nick Azarias and Libby Santos Walker are strangers with next to nothing in common except they both have spouses fighting for their lives. "Breathe" follows Nick and Libby's journey as they evolve from uneasy comrades, to unlikely friends, to even unlikelier lovers all while coping with the bleakest of circumstances. They find that life does go on after death, and that love has the power to heal, to destroy, and to define.
