It was directed and produced by Jacques-Louis Mahé,[1] a friend of Raymond Schwartz who, under the pseudonym 'Lorjak', had previously produced a silent Esperanto publicity film before World War II titled Antaŭen!

At the start of the 1960s, Mahé, a professional photographic and cinematic expert, invested in the production of the first fictional film in Esperanto.

Using a scenario by Mahé himself, the actors of the Internacia Arta Teatro (International Arts Theatre) presented a crime story, set in the Parisian periphery of petty thieves and cheats.

Mahé, who lost a large sum of money, accused Universala Esperanto-Asocio of a boycott.

At the highest point of his depression, he destroyed almost all copies: only two remain (acquired eventually by the Château de Grésillon and the British Esperanto Association, both already used) as well as the original, which LF-koop (Kooperativo de Literatura Foiro) rescued in 1991, distributing a 61-minute videotape.
