Working on Ward 17 as an agency nurse, Bron is allocated a patient, Phil Oram, who has no memory of the accident in which he lost his wife and child. When he meets Bron he does remember something — Bron attended the accident as an ambulance officer. But while he remembers Bron, she has no memory of him, nor even of attending the scene.

Plagued with guilt that she could forget a patient, Bron is placed under greater pressure when she realises that every time Phil sees her, more memories are triggered.
