When his experiments into a powerful new anesthetic go hideously awry, respected physician Dr. Jekyll transforms into the hideous Jack Hyde. As his wife Elisabeth passes her time in charitable work, rehabilitating the district's fallen women, Hyde is drawn into an escalating cycle of lust and murder that seems to know no bounds.
Edge of Sanity is a 1989 slasher film directed by Gérard Kikoïne and starring Anthony Perkins. It mixes elements of Robert Louis Stevenson's 1886 novella Strange Case of Dr Jekyll and Mr Hyde with those of tales of Jack the Ripper.
