Malcolm Webster, a nurse at an Aberdeen hospital, has a lifestyle he cannot afford, and when his wife Claire shows her displeasure at his debts, he drugs her with drugs stolen from the hospital to stop her from interfering but when she announces that she has a doctor's appointment to diagnose her lethargy, he stages a car crash in which she is killed and he apparently injured. Though playing the grieving widower at her funeral, he soon blows the £200,000 life insurance and moves to New Zealand, where he meets Felicity Drumm. She becomes his second wife, desirous of domestic bliss in their dream home, but he is already considering sending her the same way as Claire, despite the birth of their son.
