Riding atop a horse carriage while tailed and serenaded by a brass orchestra, they're drunkenly singing and shooting their way through the city's downtown.

A stutterer with a lame leg, Ivan is already up to feed the animals and waves to them warmly as he records food portion amounts while listening to early morning radio bulletins.As the drunk duo pulls up in front of Blacky's home, his pregnant wife Vera comes out to angrily usher her husband into the house while threatening to leave him "just like Marko's wife left Marko". Intoxicated Marko pulls Vera aside and lets her know that they enrolled Blacky in the Communist Party (KPJ), but she's way too angry about Blacky's irresponsible behaviour as a husband to properly process that piece of information. Blacky goes into the house while Marko proceeds on and picks up a street prostitute before disappearing into his house with her.Part One: War 1941A couple of hours later, as Sunday dawns, Ivan is making rounds at the zoo to feed the animals, hungover Blacky is eating breakfast while pregnant Vera complains about his supposed affair with a theatre actress, and Marko is preparing for sex with his prostitute as he lecherously watches her take a scrub in his bath tub. Suddenly, the roar of the planes is heard, and Nazi bombs begin falling on Belgrade.

input question: Generate a question that has the following answer: Detective Sergeant Ted Spencer for the following movie plot: Suddenly, London goes dark and loses all of its electricity. There is commotion at a cinema, with people demanding their money back. The owner of the cinema, Karl Verloc (Oscar Homolka), enters through a back entrance to the living quarters above, and pretends to have been asleep and not know anything of the blackout. His wife, Mrs. Verloc (Sylvia Sidney) comes to get him and is surprised to see him, but he informs her that he had been sleeping the entire time. He instructs his wife to return the money to the customers -- against her protests -- because he has "some money coming in." As the money is about to be disbursed to the customers downstairs, the lights go back on. It is revealed that sand was put in the boilers as an act of sabotage on London's electricity grid. The next day, Verloc meets with his contact and it is revealed that he is part of a gang of terrorists from an unnamed European country who are planning a series of attacks in London, though their exact motives are not made clear. Verloc's contact is disappointed that the newspapers mocked the short loss of electricity, and instructs Verloc to place a parcel of "fireworks" at the Piccadilly London Underground station. Verloc tells the contact that he is not comfortable with any act that would cause the loss of life. Meanwhile, Scotland Yard suspects Verloc's involvement in the plot and assigns Detective Sergeant Ted Spencer (John Loder) to investigate Verloc. Spencer is initially undercover as a greengrocer's helper next to the cinema, and befriends Mrs. Verloc and her little brother, Stevie (Desmond Tester), who lives with them, by treating them to a fancy dinner. At this point, Spencer and Scotland Yard are unsure whether Mrs. Verloc is complicit in the terrorist plots or merely innocently unaware. Verloc goes to a bird shop to meet his contact, who is actually a bomb-maker. The contact tells Verloc the time and place of where he must deliver the bomb -- all Verloc has to do is place the bomb at the Tube station at 1:45 on Saturday, as it is...???
