Legend Entertainment’s staff members and artist board a private plane to perform at an overseas. The plane ends up crashing and nine of its passengers are stranded on a deserted island. The passengers include Seo Joon Oh (Jung Kyung Ho), Ra Bong Hee (Baek Jin Hee), Jung Ki Joon (Oh Jung Se), Choi Tae Ho (Choi Tae Joon), Ha Ji Ah (Lee Sun Bin), Lee Yul (EXO’s Park Chan Yeol), Yoon So Hee (Ryu Won), Tae Ho Hang (Tae Hang Ho) and Legend Entertainment’s President Hwang Jae Gook (Kim Sang Ho).
Four months later, Bong Hee finds herself washed ashore in China with no memory of how she got there or what occurred on the island between the crash and her rescue. A special investigative committee is commissioned to find out what happened to her fellow passengers and whether anyone else has survived but it is unclear if the committee has ulterior motives for looking into the crash.
