When three-year-old Tippi Macklin goes missing on a weekend break with her parents, her face appears in newspapers around the world, sparking endless debate and conspiracy theories. Wealthy and glamorous Jed and Gabby never give up hope that ‘Little Tippi’ will be found.

Eighteen years later, a young woman arrives at their door claiming to be their lost girl. She has a new name, a new history and some startling evidence to support her claim. Can she really be Tippi – or is she an imposter?

A DNA test will prove her identity one way or the other, but when the results come back, it seems the mystery has only just begun…
