A power cut interrupts the island’s viewing of the annual Celtic v. Rangers match. Kenny begins to suspect that the B&B is haunted, his imagination fuelled by a ghost story that Alistair told them during an outing in his boat. Murdo Campbell has become reclusive and Douglas is worried about him. Unknown to the rest of the island, Elizabeth Campbell has developed Alzheimer’s dementia and Malcolm and Murdo are finding it hard to look after her. A doctor comes to see Elizabeth and recommends a nursing home on the mainland, but Murdo won’t hear of it. Elizabeth goes missing - and so does Charley. During a conversation with Gordon about the ghost, Kenny lets slip that he and Abby have separate bedrooms, which fuels intense speculation on the island about the state of their marriage Malcolm agrees that his mother must stay at home and they will do their best to look after her. Douglas finally summons the courage to propose to Mary.
