Jack's Back(1988)

“One hundred years ago, in the City of London, in the East-End slum of Whitechapel, a man shocked the world by murdering, raping and mutilating five women. He was never caught.”

A young doctor is suspected when a series of Jack the Ripper copycat killings is committed. However, when the doctor himself is murdered, his identical twin brother claims to have seen visions of the true killer.
