The first poster for Kabi is out, and it looks intriguing. Kabi is about Emperor Gojong (Park Hee-soon) after his wife Empress Myungsung is assassinated. He flees to the Russian Embassy which is where the story takes place. Apparently, Emperor Gojong has a fondness towards coffee and the Japanese use this fact to try to (I presume) poison him. Kim So-yeon plays a barista who serves the Emperor and is a crucial part in the Japanese's plan to kill the Emperor. Joo Jin-mo is also a spy working with Kim So-yeon, and Yoo-sun plays a Korean woman who has betrayed her country and now stands aligned with Japan taking a part in this conspiracy to knock the Emperor off his throne for good.
