Six decades later being adopted by an American family, Caitlin Weber embarks on a search for her Irish birth mother, only to uncover a carefully guarded secret.
Maggie O’Brien–the sole keeper of that secret–is stunned to realize that a traumatic episode she once pledged to take to her grave is now on the verge of being exposed. Maggie is determined to keep the adoption a secret from her family. When Irish social worker Clare Dolan requests a private meeting between Maggie and Caitlin, Maggie refuses. However, she agrees to let Clare share information about Caitlin’s life in America. Maggie asks Clare to tell Caitlin that she has always loved her and is glad she is doing well in America.
As Clare and Maggie engage in frequent phone conversations, a friendship develops. Maggie’s resistance eventually softens, and she agrees to consider a phone call from Caitlin. As Caitlin struggles against her mother’s resistance, she wonders how she can feel both love and shame over her existence.
Caitlin’s American brother, Dave, must face his own troubling mystery. Why did his wife, Mary, take a longer route to the airport to pick up their son, Kevin-especially on a night when black ice made the roads so dangerous, it led to the crash that took her life? As he searches for answers, Dave hopes that uncovering the truth might not only bring him closure but also help mend his fractured relationship with Kevin–offering a chance to heal their broken family.
Through it all, questions arise: Will the complex yet enduring power of family prevail? Is the will to break through the fog of uncertainty and troubled pasts strong enough for healing to occur?
