The villagers start to go down with the Cornish flu, which sends them into fits of delirium before they pass out. Only Mary and Angela appear to be immune, which means that, with an influx of tourists, they are not only running the shop but the pub and the witchcraft centre but taking visitors around the bay in Old Jake's boat, the latter with disastrous results. Alan is also exempt but frustrated as it means he is unable to have sex with Mary before going on leave.
