The Can You Hear Me? synopsis:

From ancient Syria to present day Sheffield, and out into the wilds of space, something is stalking the Doctor and her friends and infecting people’s nightmares. As Graham, Yaz and Ryan return home to see friends and family, they find themselves haunted by very different experiences. Who is the figure calling from beyond the stars for help, and why? And what are the fearsome Chagaskas terrorising Aleppo in 1380? To find the answers, Team TARDIS embark on a mission that forces them to face their darkest fears.

The 8-14 February edition of Radio Times magazine mentions the events of the episode have something to do with a “historical attack on Syria”. The warlord Timur sacked Aleppo and conquered the rest of Syria in that time period.

Written by Charlene James and Chris Chibnall and directed by Emma Sullivan, Can You Hear Me? airs Sunday, February 9, 7:10 p.m. om BBC One and 8:00 p.m. on BBC America.
