After a school video she produced goes viral, sixteen-year-old Sloane Kendrick is given a chance at a film school scholarship. She has less than two weeks to produce a second video, and she’s determined to do it. Unfortunately, she must work with Isaac Alexander, an irresponsible charmer with whom she shares an uneasy history.

On the heels of this opportunity comes a horrifying discovery: a bald spot on her head. No bigger than a quarter, the patch shouldn't be there. Neither should the bald spots that follow. Horror gives way to devastation when Sloane is diagnosed with alopecia areata. The auto-immune disease has no cause, no cure, and no definitive outcome. The spots might grow over tomorrow or Sloane might become completely bald. No one knows.

Determined to produce her video, hide her condition, and resist Isaac's easy charm, Sloane finds herself turning into the kind of person she has always mocked: someone obsessed with her looks. And just when she thinks things can't get any worse, Sloane is forced to make the most difficult decision of her life.
