But when Riley finds a birth certificate wedged in a tear in her baby book, she faces the reality that her parents might be lying to her. The birth certificate is for a baby girl with a name Riley doesn't recognize, born to parents she doesn't recognize. The baby girl - Jane O'Callahan - was born only three months before Riley, in a town a few hours away. Riley visits the town, but there is no record of Jane or her parents. Riley's parents have always been paranoid that someone was going to kidnap her. Is it because they already had? Terrified, Riley confronts her parents -- and their answer is nothing she could have expected. Riley was just a baby when her parents entered the Witness Protection Program and up until now their calm, suburban life was all but guaranteed. But now that Riley has brought Jane O'Callahan back from the dead, she fears that Jane didn't come alone.
