The Indian Doctor

Trefelin, the sleepy Welsh Valleys town in which Prem set up practice three years ago, is rudely awoken by the throaty roar of an American sports car carrying returning prodigals Basil and Robert Thomas, sons of the erstwhile local mine owner. The brothers are greeted enthusiastically by the villagers, buying drinks for all-comers and inviting everyone to their homecoming party

As the suave doctor Robert renews his acquaintance with childhood sweetheart Megan, older brother Basil ingratiates himself with villagers eager to exchange their house deeds as a deposit on a swanky house in his new development. Robert, meanwhile, surprises Prem by offering him a central role as part of his new medical centre team.

Sian decides that farmer Ceri might be worth ensnaring with her feminine charms - at least if he really has come into some unexpected money - and Robert is doing his best to woo his old girlfriend Megan, much to Emlyn's alarm. The Dawkins are not the only couple to fall out, as Prem confronts Kamini over a job offer from Basil.

Basil's continuing drive for villagers to exchange their deeds for new houses is reaping great results, and a visit to Sian's shop suggests he may be in for an unexpected investment from an unlikely source. Robert takes advantage of Emlyn's absence by taking Megan for a drive. Below ground, the trapped men each battle with their demons.

Robert pleads with Megan to leave Trefelin with him, but it's down to Prem to discover the real truth about his past. Dan helps Kamini find out the real story behind Basil's plans for the new Trefelin, leading Prem to confront him about the brothers' real reason for returning home.
