Carmela è una bambola (1958)

The daughter of a former Neapolitan gangster, Carmela has a law degree and is set to marry an aristocrat, as her father wishes. However, she suffers from a strange form of sleepwalking: at night, she goes to the room of Totò, a young man she is completely indifferent to and who is also her father's enemy. After consulting a doctor to find out the reason for this embarrassing anomaly, Carmela realises that Totò is actually the man she is unconsciously in love with.
