Now in its third year, World War 2 still rages, taking its toll on everyone. On the home-front, the Mulligans continue to face war-related challenges . . . and patience wears thin.

Margaret is pulled in various directions as she attempts to care for her toddler and disabled husband Brian, who's haunted by mistakes made on the battlefield--and their marriage is put to the test. Colleen is still pursuing her Hollywood career, but will the arrival of her baby change everything? And with Navy pilots being shot down daily, will Geoff escape the odds and make it safely home?

Bridget still serves as an Army nurse in the Pacific front, where not only her life, but health and heart are in harm's way. Molly continues to do her part to help her family and find her place in the world, but when her relationship with Patrick gets shaken to the core, she heads off on a journey that leaves her family conflicted.

The war will eventually end, but will the Mulligan family remain intact when it does?
