La figlia del diavolo or La fille du diable is a 1952 French-Italian historical drama film directed by Primo Zeglio and starring Massimo Serato, Paola Barbara, and Marina Vlady.

The so-called Baron Tucci, on a recommendation from England, arrives at the home of Count Sereni, a notable liberal.

But he turns out not to be a patriot who has returned to Italy to take part in the fight but a degraded Bourbon official who has been promised rehabilitation if he can succeed as a spy.

Tucci discovers old Sereni's second wife is one of his former lovers and persuades her to murder her husband so as to gain his inheritance.

On hearing the news, the spy contacts the police, who arrest the girl's fiancé, a young doctor, one of the leading patriots.
