David Clive has set up a new life with his girlfriend Jennifer. When his ex-wife Lorna announces her arrival, his head starts spinning, and the Shepherds are caught in the crossfire.

A mysterious note with ambiguous wording arrives for Erik, strongly encouraging him to meet in the bar at 4pm. He and Ann speculate whether the note could be used as blackmail for Erik's indiscretions or Ann's murky past. The situation worsens as the Woolleys and Mervishes also receive matching anonymous notes and arrive at the appointed time to face their accuser as a sudden storm rages outside.

Simultaneous arrivals in Aghios Nikolaos create an unbearable strain on the Shepherds' marriage. Erik is tempted by the alluring young Jocasta with whom he has shared a previous flirtation, while Donald Culley returns to continue the relationship he and Ann started.
