David helps his friend run away from home, but the handyman inadvertently leaves the young boy with a complete stranger. The Aidensfield Arms offers paintings as well as pints during an art exhibition, and Jack and Bernie take advantage of the artistic atmosphere in an ill-advised attempt to encourage Gina's creative ambitions. Elsewhere, Peggy has a go at dog training.

When a woman is involved in a hit-and-run following a local dance, Miller finds himself racing to discover the identity of the culprit. Meanwhile, David decides he has had enough of Peggy's miserly ways and walks out on the taxi service.
