Drunk drivers and car thieves, among other miscreants, are no match for the high-speed police interception units profiled in this documentary series. Officers from a number of law enforcement units dotted around the United Kingdom are shown patrolling their jurisdictions and keeping the streets as safe as possible. Cameras capture intense motorway chases and interactions with suspects, and also lighter moments that give viewers a sense of the officers' personalities away from their pressure-filled jobs.
