But when it comes to her personal life, Julie seems to have no insight whatsoever. She has worked hard to keep her marriage fresh and to be a good mother, so it's a mystery when Leo, her husband of twenty years, decides to defect from their life together and their three children: Gabe, Caroline and Aury. In his absence, Julie is diagnosed with a serious illness, which drives her children to undertake a dangerous journey to find Leo-before it's too late.

As the known world sinks precariously from view and leaves them all adrift, the Gillis clan must navigate their way through the trenches of love, guilt and betrayal, back to solid ground and a new definition of family.
