Another season of Peaky Blinders is almost here, which means there's another group trying to come for Tommy Shelby (Cillian Murphy) and his empire. From the looks of the Season 5 trailer, it appears this new threat — a Scottish gang known as The Billy Boys — is going to be even more dangerous than the Italians of Season 4.

Of course, it's not just a new threat that signals Tommy's reign could be coming to an end. His mental state seems more fragile than ever in the new episodes, and he could become his own worst enemy when it comes to keeping the Peaky Blinders, and himself, safe. It's naturally a great time for Tommy to be falling apart, because aside from gang warfare, he's also trying to keep the Blinders afloat after the financial crash of 1929. He gets an interesting proposition in the trailer, which looks like it will have ramifications for everyone around him.

Will this be the season that finally does the fearless leader in, or can Tommy Shelby manage to come out on top once more?

Peaky Blinders Season 5 premieres Friday, Oct. 4 on Netflix.
