Mia might look like a Millennial but she was born yesterday. Emerging from a coma with short-term amnesia after an accident, Mia can't remember her own name until the Siri assistant on her iPhone provides it. Based on her cool hairstyle (undercut with glamorous waves), dress (Prada), and signature lipstick (Chanel), she senses she's wealthy, but the only way to know for sure is to retrace her steps once she leaves the hospital. Using Instagram and Uber, she arrives at the pink duplex she calls home in posts but finds Max, a cute, off-duty postdoc supplementing his income with a house-sitting gig. He tells her the house belongs to JP, a billionaire with a chocolate empire. A few texts later, JP confirms her wildest dreams: they're in love, Mia is living the good life, and he'll be back that weekend.

But as Mia and Max work backward through her Instagram and across Los Angeles to learn more about her, they discover a surprising truth behind her perfect Instagram feed, and evidence that her head wound was no accident. Who was Mia before she woke up in that hospital? And is it too late for her to rewrite her story?
