Hi. I reckon it is a movie from the 80’s or 90’s, a scary one.
This Morgana woman commits a murder, but this powerful man-devil wants to protect her and reach her, so he surrenders himself to the police saying he committed that crime.
Once in jail, he reveals himself as the Devil to his prison mates, and one of them – a skeptical one -, asks him to grant him the wish to let himself get out from jail. He obliges by making him pass through the bars but shattering his body in the process. Naturally the other witnesses are terrified by this.
Another bit that I remember is this man-devil saying to someone something like: “tell Morgana I am waiting longingly”.
Thank you in advance for your help.
