Tempting Fate (1998)

"Three individuals. Two worlds. One fate..."

Ben Creed, a doctor still mourning the death of his love, meets a man who's created a machine that can transport anyone to a parallel world. For a chance to see his beloved Melody again, Ben risks everything and uses the machine. In this new—at once familiar and foreign—world, Ben meets an alternate Melody, but after he explains himself, she's uninterested in returning to his dimension.
