La moglie vergine, internationally released as The Virgin Wife, Valentina and You've Got to Have Heart, is a 1975 Italian commedia sexy all'italiana directed by Marino Girolami (here credited as Franco Martinelli).

Tension mounts when Giovannino's brother Gianfranco arrives with his insatiable German wife Brigitte.

Valentina's mother Lucia also turns up to encourage her increasingly stressed daughter who, after a fierce family argument, runs out to the lakeside.

Afraid she might attempt suicide, Giovannino and Lucia take a motor boat in search of her, but it runs out of fuel.

A ferocious storm breaks and a young French tourist finds the soaked and shivering Valentina.
