Everything you need to know about 'BTS: The Return,' the new Netflix documentary

On Friday, Netflix will release a documentary about the biggest band in K-pop, BTS

NEW YORK -- All seven members log onto a livestream, broadcast from a beach. A few years ago, it was a common image. But after the K-pop boy band BTS pressed pause on their full-band duties for nearly four years, it was revelatory.

That's the scene that begins “BTS: The Return,” a new Netflix documentary from director Bao Nguyen (“The Stringer,” “The Greatest Night in Pop”), produced by This Machine (“Martha,” “Karol G”) and HYBE, the South Korean entertainment company behind BTS and countless other international acts.

The mostly-Korean language film offers an intimate look at BTS' journey to their latest album, “ARIRANG,” released Friday. It also follows the seven member group — RM, Jin, Jimin, V, Suga, Jung Kook and j-hope — as they learned to reacclimate to their life in the fast lane, together again.

Here are key takeaways from the documentary film, which premieres on Netflix on Friday, March 27.

As BTS fans are well aware, “ARIRANG” is the band’s first full-length release since all seven members completed South Korea’s mandatory military service. In South Korea, all able-bodied men aged 18-28 are required by law to perform 18-21 months of military service under a conscription system meant to deter aggression from North Korea.
