In this tongue-in-cheek horror film by Slobodan Sijan, a pudgy, overly sensitive street vendor sells red carnations to the public, mainly female, and is generally quite friendly -- unless someone ridicules his flowers; then he strangles them. He also has a "mum" at home that has never seen a good day in her life, and his crimes may go undetected because the police inspector is successful only by accident. Muddying the confusion is a second strangler with more than one maladjustment. Sijan has inserted filmic references to other horror movies -- such as the 1931 with Boris Karloff and from that same year, with Peter Lorre -- for some extra zip in the action.
