The Count Franchi discovers that his brother (who has a psychic link to him that makes him feel all his pleasure and pain) is still alive. He enlists his help to defeat a a dictatorial usurper named Jonatto.
I've covered the 1941 version of THE CORSICAN BROTHERS already as part of this series, and the fantastic content remains the same; the psychic link between the two brothers is the fantasy element. I don't know whether this movie is a sequel to a specific movie version of the story or to the original Dumas novel, but I don't really get the impression it does much more than reiterate the themes of the original story. Still, I found it entertaining enough; Richard Greene does a good job in a dual role, and it's always fun to see Raymond Burr and Lee Van Cleef as the villains. The movie also features Nestor Paiva and Clayton Moore.
