I should also mention that downloading from unauthorized sources might not only be illegal but also risky because of phishing or malware. So, emphasizing the risks there is important.
Also, maybe the user is in a country where "Tenet" isn't available in Hindi streaming, so they need an alternative. But again, the best way is to suggest official sources first.
Let me start by recalling that "Tenet" is a Hollywood movie directed by Christopher Nolan, and it's available in multiple languages, including Hindi. The user is interested in a dual audio version where both Hindi and English audio tracks are present. Maybe they want to watch it in Hindi but have the English track as well, or toggle between them? Not sure, but dual audio is common in certain regions.
