A teacher can be a mentor, a guide and in rare cases, even a friend. Hickhi is the story of one such teacher. What makes Rani mukerji different from other teachers is her tourette syndrome. She makes hics and click noises due to neurological disorder that she explains with spirit and wit. She fights the odds. The placement of the wha wha and chak chak sounds in particular is most interesting.
Overall her acting is what makes the movie more interesting.
