在战前的纳粹德国，放映员赫尔曼·温克勒在放映主片之前被迫播放宣传片。但电影院里的老鼠一直在干扰放映，因此赫尔曼被党卫军给了最后的警告。 当最新的纳粹电影放映时，老鼠们切掉了正在放映的电影，用投射光束在大屏幕上表演了一场皮影表演。

In pre-war Nazi Germany, projectionist Hermann Winkler is forced to screen propaganda films before the main features. But the rats of the cinema have been disrupting the screenings and Hermann is given a final warning by the SS. While the latest Nazi film is being projected, the rats cut the film and use the projector beam to perform a shadow play cabaret on the big screen.
