Charming Regina Lampert (Audrey Hepburn) returns to her home in Paris from a skiing holiday to find that her world had 
been turned upside down. To begin with, her husband Charles is lying dead in the mortuary, murdered in cold blood. Then, Inspector Edouard Grandpierre (Jaques Marin) of the French Police grills her about a quarter of a million dollars her husband was supposed to have been carrying. CIA agent Bartholomew (Walter Matthau) calls her in for questioning, warning her that the money was stolen by Charles and his friends during World War II and had to be returned to the United States Treasury. Regina doesn’t have the foggiest idea about the money.
s if this isn’t enough, three seedy-looking characters who claim to be Charles’ friends keep popping up unexpectedly, threatening her with dire consequences if she does not disclose the whereabouts of the money. Nobody, except the kindly Peter Joshua (Cary Grant) - a stranger who appears from nowhere - seems to believe her innocence.
Suspicion and fear reign high as one by one Charles’ one-time partners in crime are murdered. Peter too keeps her guessing about his identity. Chased, threatened and frightened to death, Regina is left with no choice but to run, which she does - but headlong into more trouble and danger. Faced with the possibility of a cruel death, Regina is left wondering whom she could trust and whether she would ever find out where Charles had stashed the booty.
