Middle-aged Josh and Maisie Evans lead an unassuming life. When Auntie Flo, who has lived with them for years, dies and leaves them her Estate, they head to Italy on holiday. There, they meet Mrs Fingal. A wealthy widow, she lives with her grown-up niece Lena and it's pretty clear that neither is happy with the situation. So when Josh and Maisie bond with Mrs Fingal it's only natural that they all decide she should move in with them once home. It suits everyone. Beneath the suburban respectability of cups of tea and gen- teel chitchat, however, emerges a different tale: one of ruthless greed and exploitation, and suffocating, skin-crawling terror.
