Constantine Season 1 Vietsub — Fast & Instant

First, I should mention that Constantine is a TV series based on the DC Comics character John Constantine, who is a supernatural detective. The user wants it in Vietnamese, so the piece should be in Vietnamese but the instructions here are in English. Wait, no, the user provided the query in English but wants the final answer in Vietnamese? The initial query is "complete piece about: 'constantine season 1 vietsub'", so the answer should be in Vietnamese with the subject being the first season of Constantine with Vietnamese subtitles.
