Ave Maria is a film set in 1936. It stars the famous opera tenor Beniamino Gigli and a German film star of the time Käthe von Nagy.
Gigli plays a wealthy, famous and older opera singer who is grieving for his dead wife, a devoted French girl. Each year he comes to Paris to visit her grave, but is forced to go through with a concert his manager has arranged. The manager visits a seedy night club and, while drunk, tells a cabaret entertainer and her lover of that the singer is very unhappy and also wealthy.
The scheming night club girl played by Käthe von Nagy meets and accompanies the singer to Naples, pretending to be upset about his wife's demise. The singer and the girl are later engaged, but he discovers her lies and she, now genuinely in love with him, drives away in a car, but is badly injured in a resulting serious car crash. The singer, now aware of her repentance and true affectation for him, takes her for his bride.
