Download movies to offline from my server Plex to my Nvidia Shield



Hi, I have my Plex running externally on my server and I have Plex app on my Nvidia Shield. Unfortunately my internet connection is not strong enough to stream full quality of 20Gb+ movies. Is there any posibility how to download movie from my Plex server to Nvidia Shield and then watch it locally? So I can download it before I'm going to watch it. Is there such possibility? I do not have Plex Pass, but if this will allow me to download content locally I'll buy lifetime licence.

Thank you
