Ray and Lisa are soul mates and on the night of their engagement Ray collapses and has to be hospitalised. He falls into a coma and is told that if he is to live he must have a heart transplant. When it looks like all hope is lost a donor is found. After the transplant it looks like a whole new beginning for the couple and it certainly is as when Ray comes around from the operation he is behaving like an entirely new person and having flashbacks about a life that is not his own.
