Ally and Neal return from their honeymoon in Italy, expecting to settle into newlywed life-only to be shattered by tragedy. Ally's niece, Rachel, has been killed in a devastating car accident that also claimed the life of her boyfriend, Evan.

As authorities struggle to make a positive identification, Rachel's parents are asked to submit DNA samples. Wanting to help, Ally submits her own DNA through a law-enforcement database. She never expected the results to change everything she thought she knew.

The test reveals a chilling truth: Ally is not her father's biological daughter.

Certain there must be a mistake, Ally retests. There wasn't a mistake.

When she confronts her mother, the truth finally surfaces. Years ago, Gloria didn't know whether Ally was her husband's child-or her lover's. She chose silence, burying the secret and hoping it would never come to light. Now, that secret threatens to unravel everything.

Forced to question her identity and her past, Ally must decide: should she search for the man who may be her biological father, or leave the truth buried where it belongs?
