A scorchingly hot summer leads to a severe water shortage in Dibley. When the water company announces plans to put a reservoir in the village, Geraldine decides it's time to take drastic action.

The villagers want to celebrate Geraldine's 40th birthday, so they buy her a ticket to a speed dating evening. However, when she goes it turns out that most of the dates are the other villagers. When the Vicar goes home without a man, Hugo offers to sleep with her and impregnate her so she can have a baby. Meanwhile, Geraldine is trying to get the villagers enthusiastic about the 20th anniversary of Live Aid and encourages them to write to the Prime Minister about the Make Poverty History campaign. However, when they show no interest, she shows them a short video depicting two poverty-stricken children. Guest starring Miranda Hart and Cristian Solimeno.
