In the poster, a crew of well-dressed, handsome men take a walk out in the woods, smiling with one another like they're all chummy; but some of them are holding sharp-looking swords and a bow! 

The cast shown below includes Park Seo Joon, ZE:A's Hyungsik, Do Ji Han, SHINee's Minho, Jo Yoon Woo, and BTS's V. The story will tell the tale of a group of "Hwarangs", or young men studying and training together, during the Silla dynasty. 

It airs this coming December!
