Throughout the 1950s, Bronson spent most of his early acting career performing in TV shows as well as small parts in films, until he landed the lead in this ABC series. This is the only series in which he played the lead role. He would go on to have supporting roles either as a guest star or a recurring character in dozens of TV shows after this series was cancelled.
Bronson portrayed Mike Kovac, a former World War II combat photographer freelancing in New York City who specialized in getting the photographs that other lensmen could not. He usually assists newspapers, insurance companies, the police and private individuals, all of whom want a filmed record of an event.
By often acting as a private eye, Kovac gets himself into plenty of trouble involving criminals of every kind, helping with cases the police could not handle.
Besides an array of cameras for normal use, for surreptitious work Kovac employs cameras hidden in a radio, cigarette lighter and even his necktie. He also has a phone in his car, and a portable darkroom in the trunk where he could develop his negatives on the spot.
