The Dutch Hotel is getting ready for Halloween. The Jones family, who manage the hotel, have an even more important event - the arrival of Grandma from Cyprus. Her name is Eleni, and she is not short of opinions about everything. She also reveals some of Mum's secrets (Mum's name is Angeleki) and the kids, Nafsi and Yogi, want to learn more. Why was mum afraid of ghosts when she was young? And why is she so against all superstition now?
