Avalude Ravukal (transl. Her Nights) is a 1978 Indian Malayalam-language drama film directed by I. V. Sasi and written by A. Sheriff. The film explores the life of Raji (Seema), a teenage prostitute and those of the people around her. Upon release, the film received less audience in the first three days but the situation changed in the coming days and it became one of the highest-grossing films of the year. The plot follows a sex worker who has not only been unapologetic about what she does but also considers herself deserving of love and dignity despite her job.It is considered one of the boldest Malayalam films of all time. Sasi, the experimental and the most popular director at that time, tried to highlight a theme which most mainstream directors are afraid to get into. Kamal Haasan and I. V. Sasi made guest appearances in the film. The film was dubbed and released in Tamil as Avalin Iravugal and in Hindi as Her Nights and were also successful at the box office. It was remade in Kannada as Kamala (1979) and in Hindi as Patita (1980).
