Inspired by one of the longest and bloodiest real-life events in police history, Officer Mike Chandler and a young civilian passenger find themselves under-prepared and outgunned when fate puts them squarely in the crosshairs of a daring bank heist in progress by a fearless team of highly-trained and heavily-armed men. While on a routine patrol, an aging cop, his partner and their ride-along, get caught in a standoff with a band of former mercenaries robbing a bank.
