Petrov isn’t doing well. It’s nighttime, he’s on a bus at night, and he’s got a fever. He sees, and takes part in, things that probably, hopefully, aren’t actually happening: violence, murder, weird, weird shit. The people around him may not have come down with the flu, but the snippets of conversations he hears are just as weird and ominous: the people are highly unpleasant, they’re selfish and paranoid and judgmental, happy to throw each other to the wolves. If Petrov wasn’t ill, he might even almost be relieved when the FSB stops the bus, drags him off and throws him into a van – but it turns out that while this episode really does seem to happen, it’s not the FSB but a bunch of mates of Petrov’s. Oh, and a coffin with a dead person inside. It’s one of those nights, and it’ll only get stranger.
