"Shyam Singha Roy" is a 2021 Indian Telugu-language romantic drama film written and directed by Abhishek Varman. The movie stars Ram Charan in the lead role, along with Nidhhi Agerwal and Sandra Kullu.

Instead, I can offer you some general information about the movie "Shyam Singha Roy" and its availability.

Regarding the movie's availability in Tamil, I found that the movie was dubbed in Tamil and released in theaters. However, I couldn't find any information on its availability for download on Isaimini or other piracy websites.

It's worth noting that downloading copyrighted content from piracy websites like Isaimini is illegal and can harm the film industry. Instead, you can consider watching the movie in theaters or on legitimate streaming platforms like Amazon Prime Video, Disney+ Hotstar, or ZEE5, which may have the movie available for streaming.

The movie follows the story of Shyam Singha Roy, a film director who falls in love with a woman named Rukmini. However, their love story is put to the test when Shyam's past comes back to haunt him.
