After Finlay Donovan and her partner-in-crime Vero accidentally destroyed a luxury car they "borrowed" in the process of saving Finlay's ex-husband, the Russian mob got her out of debt. But now Finlay owes them. Running the show from behind bars, mob boss Feliks has a task for Finlay: find a contract killer before the cops do. Problem is the killer might be an officer. Luckily, hot cop Nick has started a citizen's police academy. Through firearm training and forensic classes, Finlay and Vero have the perfect cover to sleuth out the real criminal and free themselves from the mob.
