Garson is with blue eyes and a voice different from Rajesh's. Garson uses contact lenses and gets a throat operation to portray Rajesh's voice. His unconscious body is found in an Indian sea. Rita accepts him as Rajesh, although she has some misgivings after he touches the feet of another lady instead of Rita's mother. Rita is pregnant with Rajesh's baby. Garson is given a similar mole as Rajesh. Rajesh's dog and cook realize what has happened, so Garson kills them to avoid their exposing him. The authorities are also less trusting. Will Garson be caught out or not and end up marrying the pregnant Rita? Will Rajesh manage to escape and make it back to India to expose and kill Garson?
