Shimana Periye (1977)

The main setting of the movie was a disastrous cyclone and tidal bore which attacked Bangladesh in 1970. That vast spate washed away an opulent girl and a destitute man to a secluded island where no sign of other human was found. Dumping the class-distinction, they fell in love and founded that isolated island as their paradise. Even after their rescue, brutal social prejudices could not separate them and thus they forded across that primitive fringe with the message of love and equal-ism.
