The main ghosts in 'Ghosts' are a hilarious bunch of spirits stuck in a country house, each with their own quirks and backstories. There's Julian, the disgraced politician who died pantsless and now can't interact with objects. Robin is the caveman ghost who's been around since Stone Age times and loves electronic gadgets. Mary got burned as a witch and now randomly gets sucked into the afterlife. The Captain is a WWII officer who hides his sexuality behind strict military discipline. Kitty is a bubbly Georgian era woman who thinks everything is wonderful, even her own murder. Then there's Thomas, the romantic poet who died of a broken heart and still writes terrible poetry. Fanny is the stern Victorian lady who keeps trying to scare away living residents. Pat is the scout leader with an arrow through his neck who organizes ghostly activities. They're all bound to the property and constantly meddle in the lives of the living couple who inherit the house.
