Frank Sinatra portrayed Rocco Fortunato, also known as Rocky Fortune, a young man of several talents constantly in need of employment and who accepts odd jobs from the fictitious Gridley Employment Agency., often referred to simply as "the Agency." During the course of the series, he would work as a process server, museum tour guide, cabbie, bodyguard, chauffeur, truck driver, social director for a Catskills resort and a carny, in addition to various musical jobs. These assignments typically led Rocky into situations where he would track down criminals, often rescuing people (especially women) in need of help, and ultimately needing to find yet more work. Rocky made many wise remarks, using "hep" slang of the times, and seemed to attract trouble wherever he went.
Sinatra infused the role of Rocky with a witty, tongue-in-cheek quality that acknowledged Sinatra's own career. For example, in the episode "Football Fix", Rocky begins to sing "I've Got the World on a String" while walking down the street, a song Sinatra had performed prior to playing the role of Rocky.
Aside from Sinatra, the only other recurring role on the series was that of Hamilton J. Finger, a not terribly smart but solid and dependable police sergeant voiced by Barney Phillips. Other guest roles on Rocky Fortune were voiced by actors such as Raymond Burr, Ed Begley and Jack Kruschen.
The final episode, "Boarding House Doublecross", aired on March 30, 1954, less than a week after Sinatra won the Academy Award for Best Supporting Actor for his role as Private Angelo Maggio in the 1953 film, From Here to Eternity. As a running gag towards the end of the show's run, Sinatra would work the phrase "from here to eternity" into the script as a reference to his film role in almost every episode.
