Meanwhile, her eighteen-year-old daughter Julia is falling dangerously in love, and Diane's mother, Jean, is relishing her newfound freedom as a single woman in Europe. Distracted by their individual concerns, the three women are ill-prepared for the crisis that suddenly appears on Diane's doorstep in the form of a handsome FBI agent asking about an explosive secret that's laid buried for decades.

Diane finds herself drawn into an illicit affair that threatens to erupt into scandal, while Julia's own dramatic antics endanger her life. Meanwhile, Jean is desperate to keep hidden painful memories she's guarded for so long. These three extraordinary women find that only by facing down secrets and lies can they face the future.
