It's Judgement Day in Mudcaster.
The Mother likes a decent Judgement Day. It's an excuse to give existence a good telling off. But the Mother's hormones are turning Grandmotherly, and the Father thinks she might be entering the Change. It was when the Grandmother before her entered the Change that all the dinosaurs died. It's clear she can't fight for mankind when her hormones are on the march.
To the Mother's annoyance, it's son-in-law Brian who's chosen to answer for the world's sins. Brian's a bit of a damp lettuce, if the truth be told, so what business would he have in standing up to daft gods and barmy demons? If the Mother pictures Brian as a knight of old, it's always with a tarnished shield and a drooping lance.
When Brian goes missing, and the Mother learns the Grandmother is being held captive by demons, the Father offers to take the Mother to Hell and back—what husband wouldn't?—to rescue them. The family must be reunited, else how can they stand firm together at the Trials? And Brian, being Brian, will need all the help he can get if he's really to answer for everyone's sins and save mankind from oblivion.
Burying Brian is a gentle comedy. No demons or lettuces were harmed in its writing.
