Plot Summary:

Cary Grant stars as Peter, who may or may not be a flimflam man who aids the recently widowed Regina (Audrey Hepburn) in her mission to recover a fortune hidden by her late husband. But three sinister crooks (Walter Matthau, James Coburn and George Kennedy) -- who'll stop at nothing -- also covet the loot. A cast of legendary stars has chemistry to burn in director Stanley Donen's suave comedy with an Oscar-nominated score by Henry Mancini.
