The brand new episode, titled The Story and the Engine, sees the Doctor going up against a dangerous new threat: "The Spider and its deadly web of revenge."

The Story and the Engine has been penned by Inua Ellams, a Nigerian poet and playwright best known for creating the critically-acclaimed Barber Shop Chronicles – and, fittingly enough, this episode sees Ncuti Gatwa's Time Lord meet a threatening figure named the Barber.

The synopsis for the new episode reads: "In Lagos, the mysterious Barber reigns supreme. The Doctor discovers a world where stories have power, but can he stop the Spider and its deadly web of revenge?"

Alongside his new companion, the Time Lord is joined by a wave of new guest stars in his second season in the TARDIS, with this episode including the likes of Ariyon Bakare (Mr Loverman) as the Barber and Michelle Asante (The Suspect) as Abena.

With the broadcast schedule for Doctor Who having changed in recent years, you might be struggling to keep track of when new episodes of the show are releasing on TV and BBC iPlayer.
