When Springville residents--at least the ones still alive--are questioned about what happened on prom night, they all have the same explanation--Maddy did it. An outcast at her small-town Georgia high school, Madison Washington has always been a teasing target for bullies. And she's dealt with it because she has more pressing problems to manage. Until the morning a surprise rainstorm reveals her most closely kept secret: Maddy is biracial. She has been passing for white her entire life at the behest of her fanatical white father, Thomas Washington. After a viral bullying video pulls back the curtain on Springville High's racist roots, student leaders come up with a plan to change their image: host the school's first integrated prom as a show of unity. The popular white class president convinces her Black superstar quarterback boyfriend to ask Maddy to be his date, leaving Maddy wondering if it's possible to have a normal life. But some of her classmates aren't done with her just yet. And what they don't know is that Maddy still has another secret--one that will cost them all their lives.
