Tasha, Hallie and Flo live the UK; they don't know each other. Hallie is a cystic fibrosis patient waiting for a lung transplant. Flo likes Zander, but his sister doesn't approve of the relationship. Tasha's new boyfriend is the adventurous type-- maybe too adventurous. As their lives gradually entwine there is tragedy and joy; heartbreak and hope. And from loss comes life and new beginnings, friends and families.
