Rakesh is astounded at this and goes to meet this woman, who does indeed resemble his wife. Rakesh, however, does not believe that she is his wife, as he himself had cremated her with his own hands. But this woman is adamant, the matter goes to court, which must find out whether this woman is really Geeta or an imposter, before trying her for her crimes.
