A nostalgic comedy-detective drama about spies and intelligence officers, professional and family duty, passions extinguished and reignited, and the difficult choice between love for one's country and one's loved one. It's a time when sausage cost 2.20 rubles, a glass of soda was just a penny, the sky was clearer, and the sun was brighter.

Shurik and Lidochka, sitting comfortably on one of the benches, look like they're from Gaidai's film. But take a closer look—something's clearly wrong. Shurik and Lidochka are completely different! In this alternate reality, they've become partners—Soviet intelligence officers, not superheroes straight out of a spy novel, but ordinary employees whose marriages are crumbling under the weight of secrecy. And now Lidochka's jealous husband is ready, without even realizing it, to sabotage an operation to capture a foreign spy, while she, torn between saving her marriage and saving her homeland, is trying everything at once. And suddenly, a personal tragedy becomes the best cover for a secret operation.
