Before I Hang

Sentenced to die for his role in a mercy killing, Dr. John Garth (Boris Karloff) awaits his fate behind bars by continuing a series of experiments aimed at combating the aging process. On the eve of being put to death, Garth inoculates himself with a serum made from the blood of a recently executed psychopath. As he's lapsing into unconsciousness, Garth learns that his death sentence has been commuted. Although the serum makes Garth younger, he is also overcome by a homicidal rage that leads to the murder of the prison doctor. And as he struggles to continue his experiments while spending the rest of his life behind bars, Garth must also deal with his new, homicidal alter ego.
