Also, I should consider the legality. If the series isn't available through legal streaming services in a region, users sometimes resort to piecing together parts from various sources, which could be against copyright laws. I have to be cautious not to encourage or provide methods for circumventing legal protections.
Alternatively, the user could be looking for a summary guide, like a recap of each episode from 1-12, or a discussion on the plot, characters, etc. The mention of "Hindi" suggests they want the guide in Hindi, or the series is available in Hindi with Hindi subtitles.
But I should check if there's a well-known TV series called "Smoke" from 2018. Let me think... There's a 2018 South Korean drama called "Save Me" but that's not Smoke. Maybe the user is referring to a Hindi dubbed version of an original series. Sometimes international shows are dubbed into Hindi. Alternatively, maybe it's an Indian show itself.
Wait, sometimes in India, there are local adaptations or original series that might be titled similarly. There was a show called "Smoke" that aired in India? Not sure. Alternatively, maybe it's a movie split into parts. But the user mentions "episodes join 1-12 part", which sounds like an entire season's worth of episodes split into parts. Maybe it's an online series that people have uploaded in parts on platforms like YouTube or other video sites.
Another angle: The user might want to know how to concatenate multiple downloaded parts (e.g., video segments split into parts 1 to 12) using software. Tools like FFmpeg can be used to join video files. But I need to make sure that the guide I provide is compliant with usage policies. If the original content is copyrighted, providing instructions on combining it might lead to misuse unless it's for personal use.
