Sultry nurse Claire Brightwell (Eva Pope) breezes into Cardale to shake up the practice, whilst Tom is involved in a climbing accident and Will's son Tony returns.

Newcomer Claire wastes little time in making her presence felt at the practice and tries to seduce Tom, while Will wonders how many more revelations about his son he can take.

The outbreak of a deadly epidemic puts strain on the practice, while Claire does her wicked best to drive a wedge between Alex and Tom.
