My truck wont move is it a stuck brake?

its a i think 92 Toyota pickup or something. It my girlfriends so I'm not entirely sure its manual transmission. it starts fine, you can put it in gear and everything but when you go to drive it doesn't move. it sounds like its trying to but the wheels are stuck. is that the e brake or something? if not how would i know what it is and how would i go about fixing it. links to videos or diagrams or detailed explanation would be highly appreciated.
