Produced by Elena Sangro and funded by the Commitee of Motenegrin Exiles (including the former Queen Milena), the film tells the full story of the heroic conduct of Montenegrin people during the First World War.

A killer is on the loose, murdering people with an iron claw.

A heated sporting rivalry divides Giorgio Roberti and Fausto Renzi, both capable marathon runners. After a defeat the latter contemplates abandoning competitive sports, but is convinced by Silvia Delotti, daughter of the sports organizer of the "Aurora", to return to his father's "stable". The rivalry thus also becomes sentimental between Giorgio, already in love with Silvia, and Fausto.
