As the daughter of a police officer, sixteen-year-old Cass Danner knows the importance of following rules. But in the traumatic aftermath of her parents’ sexting mistake, Cass agrees to ditch school with her best friend and fellow kid of a cop, Javier Caliendo. As the pair pulls into Barry’s Burgers to grab some lunch, they stumble onto a robbery in progress. In the confusion that ensues, the robbers jump into the car with Javi and Cass, and demand they drive away. When the robbers remove their masks, Cass is stunned to discover that one of the robbers is Elena Caliendo—Javi’s twin sister and Cass’s ex-girlfriend.
Now, having been unwittingly thrust into a dangerous plot involving the children of police officers, Cass must learn to make decisions without any clear rules to guide her. And, as the day goes on, Cass is forced to confront her feelings for both of the Caliendo twins and the complicated history between the three of them, leaving Cass to make her most difficult decision yet.
