After inheriting a beloved local pub from her mother, Molly Stratton puts it up for sale to the highest bidder, rather than selling it back to the community. She turns to Pearl for help to deal with the anonymous threats she's been receiving - including a dead seagull on her doorstep. When the pub is sold, the situation takes an even darker turn.

Dolly notices unexplained things happening in her house: the shower being left on when she hasn't used it, money going missing and then reappearing, the radio tuned to the wrong station. Pearl fears her mother is showing early signs of Alzheimer's disease, but she hooks up security cameras to placate her. What they see on the footage leads to a surprising solution to the problem.
