Season 3 of “Peaky Blinders” came to an end for British viewers Thursday night. But fans need not mourn the Shelby family. The BBC Two series was picked up for a fourth and fifth season in late May, and star Cillian Murphy is revealing what to expect for the Birmingham gang.

The hit series ended on a grim note with the entire Shelby family — Tommy (Cillian Murphy), Polly (Helen McCrory), Michael (Finn Cole), John (Joe Cole) and Arthur (Paul Anderson) — finally getting arrested for all of their crimes. Protecting his family has always been Tommy’s focus, and they’ve always trusted him to do what’s best. So, how will getting them arrested affect the family dynamic in Season 4?

“Everything has changed because I think his family think that he’s betrayed them,” Murphy told BBC Two following the finale. “It’ll be up to Tommy to demonstrate to them that he hasn’t betrayed them and that he has a bigger plan.”

Tommy has certainly had luck on his side in the past. Whether it was avoiding death by tricking Alfie Solomons (Tom Hardy) in Season 2 into thinking that he was going to blow up his business, or having Winston Churchill (Richard McCabe) pardon him from getting assassinated by the Red Right Hand. But can luck save him this time around?

Murphy added that the question going into Season 4 of “Peaky Blinders” is “what the bigger plan is.”

“Who is he gonna call?” the actor asked. “What’s gonna happen to the family? Can he ever get that level of trust or love back again?”

Season 3 of “Peaky Blinders” is currently available for U.S. viewers to stream on Netflix. No premiere date for Season 4 has been announced yet.
