Signal Over the City (Serbo-Croatian: Signali nad gradom) is a 1960 Yugoslav film directed by Žika Mitrović.
A group of Partisans, led by commander Ranko, enters the town with the objective to rescue Tomo and Pero before they succumb to torture and give away information.
Finding themselves entrapped, the Partisans decide to attempt a risky breakthrough over a bridge...
The film is based on actual events that took place on 17 November 1941, when a group of 25 Partisans led by Većeslav Holjevac, disguised in Home Guard uniforms, entered Karlovac in order to rescue Marijan Čavić, a prominent Communist Party member captured by the Ustaše.
Unbeknownst to Partisans, Čavić had already been transferred from the town hospital back to prison, so the actual raid, unlike its fictional counterpart, failed to achieve its objective.
