Bombay to Bangkok is a light-hearted romantic comedy about a boy from Mumbai and a girl from Bangkok. This boy is a chef in Mumbai. He steals something, and then realises that it belongs to the Mafia. He flees to Bangkok and poses as a doctor.
There, he falls in love with this girl, who works in a massage parlour. With her help, he tries to recover his booty which he had hidden somewhere, and had forgotten the location.
I would say this is Nagesh Kukunoor’s first masala film.
