This is a scene from the film Kin-dza-dza. The character with the bell in his nose is a representative of the losing side in the war, while the one without the bell is the winner. The same can be verified through an electronic screening system.

The humor of the situation lies in the fact that, although the differences within their society are stark, it is difficult for an outside observer to tell who is who. At one point, it seems like everyone has lost.
