Love is not an abstract idea. It is not saying I'm here for you, let me know if you need me. It’s making the decision, when someone close to you is in trouble, about what you will DO to fix as much as you can for them. It’s a doing thing. A verb.

For Callie, love is about looking after her family - her husband and two children - and their beautiful home.

For Steff, Callie’s younger sister, love is about experiencing all that life has to offer without having to ever settle down.

For Lila, Callie’s best friend, love is about finding a soulmate. And when she meets divorced father-of-two Eddie, she knows her search is over.

For Walter and Honor, Callie and Steff’s divorced parents, love is about caring for the daughters they share.

Then Callie gets some life-changing news. And suddenly the whole family is about to understand what love really, really means....
