Mother and daughter Charlie and Eva never sought social media fame, but when a stunning photo of Eva went viral, fame found them. Now, after more than two years documenting life on the road in their vintage Airstream trailer, the duo has temporarily settled on the North Shore of Lake Superior. Eva is happily finishing her senior year of high school and applying to college, but Charlie longs for the adventures they left behind.

When Eva goes missing less than a week before her graduation, it's Charlie who is immediately suspected of foul play--not just by their fans, but also by the police and the FBI. As a fight about one more road trip comes to light, and the truth about their relationship is questioned, Charlie realizes the rosy facade they portrayed online hid a complicated and potentially dangerous reality. Now, to clear her name and find out what has happened to her daughter, she'll have to confront her own role in Eva's disappearance--and whether she knows her daughter at all.
