"Ritu" could refer to several things:
* A specific film title: If you know the full title of the film, please provide it.
* A season in Hindi: "Ritu" means "season" in Hindi. There are six seasons in the Hindu calendar: Vasant (Spring), Grishma (Summer), Varsha (Rainy), Sharad (Autumn), Hemant (Early Winter), and Shishir (Winter). If you're looking for a film based on a season, specifying which one would be helpful.
* A character name: There might be a character named "Ritu" in a film. Providing more information about the film or the character would help locate the film.
Please give me more details so I can help you find the location of the film.
