The trailer starts out all happy, showing GOT7 horse-playing on a first class flight to some unknown destination. But the joyful moment is squashed in its entirety when the flight encounters some turbulence, violently lurching the aircraft in every possible direction. The scene then shifts to the boys stranded on a hazy, foggy island, lost to the world. 

What will their fate be? We'll have to find out with the full release on September 27!
