Casualty: The Road Not Taken

Zoe's day begins with a video call from old friend Maggie, inviting her to work for the air ambulance. However, it's soon down to business as two major accidents enter the ER, although things turn weird when the consultant begins to suffer recurrent bad dreams - and see her experiencing the same events more than once in a Groundhog Day-like episode, giving her the chance to make up for her mistakes during a difficult shift. Sunetra Sarker stars, with Jamie Davis, Derek Thompson and Suzanne Packer
