It creaked

A hand presses a button on a metallic device, releasing a cloud of white smoke that fills a room with a lamp and shelf. The scene cuts to two men in a dimly lit workshop, both wearing red, blood-stained shirts and gagged with red balls in their mouths, sitting side by side and looking forward. The camera then focuses on a man in a white hat, who looks up with a surprised expression, with a large glass flask containing a red liquid and a goldfish visible in the foreground. The scene returns to the two men, now shown in a closer shot, still gagged and seated, with the man on the right grimacing.
