In the world of “ Stop That Train ,” (opening in theaters on June 12) RuPaul is Madame President, and like any world leader, she worries about her approval ratings. When a high-speed train called the Glamazonian Express is struck by lightning and hurtles toward disaster – a threatening “stormaganza” – the president is put to the test. Best friends Tess (Ginger Minj) and DeeDee (Jujubee) play train stewardesses who trade their dreary shifts on the Stank Rail for the glitzy Glamazonian Express.
