After the intro, Steve Mitchell would be summoned to the office of 'The Commissioner', the regional head of an unnamed US State Department agency created to address international unrest as it affected U.S. interests.
Steve's cover identity, in almost all his adventures, was that of a suave debonair foreign correspondent for an unnamed print publication — his assignments invariably involved deceit, trickery, and violence, all tied together into a successful resolution by the end of the episode.
Many stage and screen actors appeared as guest-stars including, among many others, William Conrad, Raymond Burr, Paul Frees, Jim Davis, Dan O'Herlihy, Richard Boone, and Eddie Cantor.
[4] Episode titles became fairly standardized, starting with a verb, and describing the assignment: Find Szabo and The Briefcase, Keep Chromite Mine Operating, Intercept Dr. Korvel Before Opposition, etc.
Produced by Grace Gibson Transcriptions, this version of Dangerous Assignment re-did 52 episodes of the full American run, with Lloyd Burrell playing Steve Mitchell — this radio series was broadcast in Australia in 1954 to 1956 and the following years.
Among the more famous guest stars were Hugh Beaumont, Paul Frees, Elena Verdugo, Harry Guardino, Lyle Talbot, John Dehner, Michael Ansara, Jim Davis, and Strother Martin, many of them appearing as different characters in different episodes.
