A trail of counterfeit hundred dollar bills has been discovered in several places around the world. When this comes to the attention of the Secret Service, they assign one of their top men, Pete Novak (Yul Brynner), to the case of finding out who is producing and distributing them.
Pete realizes that this is an assignment that demands his full attention, so he immediately breaks up with his girlfriend in preparation for the journey he must take. Before Pete can even begin his search, he is ambushed by a gang of hoodlums trying to shoot him down as they drive by outside his home. He concludes that the gang must have been tipped off by someone on the inside of the service about his new assignment. He manages to kill them, but discovers afterwards that the killers has accidentally shot and killed his ex-girlfriend in the process.
The killing of the girlfriend makes the whole assignment very personal for Pete. To begin the search for the counterfeit distributor, he travels across the Atlantic to London, England, to visit Scotland Yard headquarters, since they are in charge of the counterfeit investigation in Europe. There, he meets up with Superintendent Sloane (John Barrie) of the Yard, who arranges for him to be partnered by an investigator by the name of Arthur Thompson (Edward Woodward). Arthur is a very happily married jolly old (fairly young, actually) copper, who manages to ignore all of Pete’s remarks about the inappropriateness of being a married man working as an agent or policeman.
Pete and Arthur start infiltrating the counterfeit organization, posing as members of the Golden Goose gang - a gang that has been all but erased from the face of the earth by the police. They use their fake identities to hide their undercover infiltration from the head of the illegal operation, The Owl Harrison (Charles Gray), and are ultimately successful in stopping the counterfeit operation (except that Arthur is killed by the gang and the Owl is not really the head of the gang, although I can't blame anyone for not watching to the end).
New York City private eye P.J. (Peter Joseph) Detweiler needs the work, so he accepts an offer to be a bodyguard to protect Maureen Preble, the mistress of shady millionaire William Orbison.
Orbison takes the family to the Bahamas, where a romantic attachment between P.J. and the married Maureen seems to be growing. Orbison's business partner, Grenoble, is shot dead and P.J. is arrested by the police. It becomes clear to P.J. that he has been set up by the Orbisons, who wanted to rid themselves of Grenoble and needed a fall guy.
P.J. is released by the authorities and makes it back to New York, where he confronts the masterminds of the plot. About all he can do is stand by as Orbison and his mistress end up doing away with one another.
Victor Frankenstein, a cold, arrogant and womanizing genius, is angry when his father forbids him to continue his anatomy experiments. He ruthlessly murders his father by sabotaging the old man's shotgun, consequently inheriting the title of Baron von Frankenstein and the family fortune. He uses the money to enter medical school in Vienna, but is forced to return home when he impregnates the daughter of the Dean.
Returning to his own castle, he sets up a laboratory and starts a series of experiments involving the revival of the dead. He eventually builds a composite body from human parts, which he then brings to life. The creature goes on a homicidal rampage until it is accidentally destroyed when a vat where it has been hidden is flooded with acid.
Jim "Lucky" Moore (Allan Jones), an insurance salesman, comes up with a novel policy for his friend, Steve (Robert Cummings): a 'love insurance policy', that will pay out $1-million if Steve does not marry his fiancée, Cynthia (Nancy Kelly). Encouraged by Jim's argument that Jim has never had to pay out on a policy so that the marriage is a sure thing, Steve accepts.
The upcoming marriage is jeopardized by Steve's ex-girlfriend, Mickey (Peggy Moran), and Cynthia's disapproving Aunt Kitty. The policy is underwritten by a nightclub owner, Roscoe (William Frawley), who sends two enforcers – Abbott and Costello – to ensure that the wedding occurs as planned.
Everyone involved in the situation winds up sailing or flying to San Marcos (a fictional South American country), where another complication arises, when Lucky falls for Cynthia. Lucky winds up marrying Cynthia, but Roscoe does not have to pay the $1-million because Steve ends up marrying Mickey.
