Harry is hosting a Greek wedding reception at the Plaza Suite but has no idea how to make the Greek dishes such as kleftico, which the bride's mother insists upon.

Ken and Margaret are employed by Keith Filkin, a newspaper reporter, to act as minders for Dorothy North, a naive Scottish woman who has just been released from prison after serving 15 years (!) for passing on state secrets. A man from MI5 is waiting to talk to her as she emerges from prison, but Filkin gets to her first and drives her away. After rival newspapers get wind of the story, the Plaza Suite, where she takes refuge, is besieged by reporters. When Dorothy wants to terminate the contract with the paper, the newspaper starts to get very possessive and even threatens that if she breaks the contract she'll go back to prison. Rocky dresses up as Dorothy (!!) and runs out of the Plaza Suite to distract the reporters' attention while Ken and Dorothy make their escape. Ken hands her over to the MI5 man.
