The Jessop family are taking their post-lockdown "summer holiday" a little later than usual, as they head to a chilly Margate in the BBC festive special Pandemonium.
Katherine Parkinson (The IT Crowd) leads the cast as mum Rachel, who hopes that a last-minute family break will make up for their cancelled summer plans.
Read on for a guide to the cast and characters in Pandemonium.
