Rocky and Dan, war buddies, are prowl car cops on night duty. Dan is a cynic who views all lawbreakers as scum; Rocky feels more lenient. Both are attracted to the radio voice of communicator Kate Mallory; but in person, Kate proves reluctant to get involved with men who just might stop a bullet. By lucky chance, Rocky and Dan cause big trouble for murderous racketeer Ritchie Garris; but when he swears vengeance, Kate's fears may prove justified.

When the daughter of veteran 911 call center operator Pamela, and her estranged husband Jeremy, a Senior Police Officer, is kidnapped and held hostage, they are left desperate, with no choice but to follow the kidnapper's rules: send messages through dispatch for all police and fire units to scatter to remote locations throughout the city where they are met with chaos. Not knowing who or why, they must race against the clock to make the choice of their lives: save the city — or save their daughter.
