In New York, a domestic disturbance takes a violent turn which changes a police chief's life; in Florida, an officer is separated from his K-9 while chasing two suspects; in Indiana, an officer stares down the barrel of a suspect's gun.

Arkansas police stop a knifeman enraged over a midnight pot roast; in Delray Beach, Fla., officers must rescue two children teetering on a ledge with their mother who is high on drugs; in Utah, a trespasser attacks an officer with his own baton.
